Dots in the column names cause an error in the ingest
pipeline, as dots are special characters in ingest pipeline.
This PR changes dots into underscores in CSV field names
suggested by the ML find_file_structure endpoint _unless_
the field names are specifically overridden. The reason for
allowing them in overrides is that fields that are not
mentioned in the ingest pipeline can contain dots. But it's
more consistent that the default behaviour is to replace
them all.

When analysing a semi-structured text file the
find_file_structure endpoint merges lines to form
multi-line messages using the assumption that the
first line in each message contains the timestamp.
However, if the timestamp is misdetected then this
can lead to excessive numbers of lines being merged
to form massive messages.
This commit adds a line_merge_size_limit setting
(default 10000 characters) that halts the analysis
if a message bigger than this is created. This
prevents significant CPU time being spent subsequently
trying to determine the internal structure of the
huge bogus messages.
This change helps to prevent the situation where a binary
file uploaded to the find_file_structure endpoint is
detected as being text in the UTF-16 character set, and
then causes a large amount of CPU to be spent analysing
the bogus text structure.
The approach is to check the distribution of zero bytes
between odd and even file positions, on the grounds that
UTF-16BE or UTF16-LE would have a very skewed distribution.
This change fixes a race condition that would result in an
in-memory data structure becoming out-of-sync with persistent
tasks in cluster state.
If repeated often enough this could result in it being
impossible to open any ML jobs on the affected node, as the
master node would think the node had capacity to open another
job but the chosen node would error during the open sequence
due to its in-memory data structure being full.
The race could be triggered by opening a job and then closing
it a tiny fraction of a second later. It is unlikely a user
of the UI could open and close the job that fast, but a script
or program calling the REST API could.
The nasty thing is, from the externally observable states and
stats everything would appear to be fine - the fast open then
close sequence would appear to leave the job in the closed
state. It's only later that the leftovers in the in-memory
data structure might build up and cause a problem.
This change contains a major refactoring of the timestamp
format determination code used by the ML find file structure
endpoint.
Previously timestamp format determination was done separately
for each piece of text supplied to the timestamp format finder.
This had the drawback that it was not possible to distinguish
dd/MM and MM/dd in the case where both numbers were 12 or less.
In order to do this sensibly it is best to look across all the
available timestamps and see if one of the numbers is greater
than 12 in any of them. This necessitates making the timestamp
format finder an instantiable class that can accumulate evidence
over time.
Another problem with the previous approach was that it was only
possible to override the timestamp format to one of a limited
set of timestamp formats. There was no way out if a file to be
analysed had a timestamp that was sane yet not in the supported
set. This is now changed to allow any timestamp format that can
be parsed by a combination of these Java date/time formats:
yy, yyyy, M, MM, MMM, MMMM, d, dd, EEE, EEEE, H, HH, h, mm, ss,
a, XX, XXX, zzz
Additionally S letter groups (fractional seconds) are supported
providing they occur after ss and separated from the ss by a dot,
comma or colon. Spacing and punctuation is also permitted with
the exception of the question mark, newline and carriage return
characters, together with literal text enclosed in single quotes.
The full list of changes/improvements in this refactor is:
- Make TimestampFormatFinder an instantiable class
- Overrides must be specified in Java date/time format - Joda
format is no longer accepted
- Joda timestamp formats in outputs are now derived from the
determined or overridden Java timestamp formats, not stored
separately
- Functionality for determining the "best" timestamp format in
a set of lines has been moved from TextLogFileStructureFinder
to TimestampFormatFinder, taking advantage of the fact that
TimestampFormatFinder is now an instantiable class with state
- The functionality to quickly rule out some possible Grok
patterns when looking for timestamp formats has been changed
from using simple regular expressions to the much faster
approach of using the Shift-And method of sub-string search,
but using an "alphabet" consisting of just 1 (representing any
digit) and 0 (representing non-digits)
- Timestamp format overrides are now much more flexible
- Timestamp format overrides that do not correspond to a built-in
Grok pattern are mapped to a %{CUSTOM_TIMESTAMP} Grok pattern
whose definition is included within the date processor in the
ingest pipeline
- Grok patterns that correspond to multiple Java date/time
patterns are now handled better - the Grok pattern is accepted
as matching broadly, and the required set of Java date/time
patterns is built up considering all observed samples
- As a result of the more flexible acceptance of Grok patterns,
when looking for the "best" timestamp in a set of lines
timestamps are considered different if they are preceded by
a different sequence of punctuation characters (to prevent
timestamps far into some lines being considered similar to
timestamps near the beginning of other lines)
- Out-of-the-box Grok patterns that are considered now include
%{DATE} and %{DATESTAMP}, which have indeterminate day/month
ordering
- The order of day/month in formats with indeterminate day/month
order is determined by considering all observed samples (plus
the server locale if the observed samples still do not suggest
an ordering)

This adds the node name where we fail to start a process via the native
controller to facilitate debugging as otherwise it might not be known
to which node the job was allocated.
Moves the test infrastructure away from using node.max_local_storage_nodes, allowing us in a
follow-up PR to deprecate this setting in 7.x and to remove it in 8.0.
This also changes the behavior of InternalTestCluster so that starting up nodes will not automatically
reuse data folders of previously stopped nodes. If this behavior is desired, it needs to be explicitly
done by passing the data path from the stopped node to the new node that is started.
Re-enable muted tests and accommodate recent backend changes
that result in higher memory usage being reported for a job

This corrects what appears to have been a copy-paste error
where the logger for `MachineLearning` and `DataFrame` was wrongly
set to be that of `XPackPlugin`.
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.

Improve the hard_limit memory audit message by reporting how many bytes
over the configured memory limit the job was at the point of the last
allocation failure.
Previously the model memory usage was reported, however this was
inaccurate and hence of limited use - primarily because the total
memory used by the model can decrease significantly after the models
status is changed to hard_limit but before the model size stats are
reported from autodetect to ES.
While this PR contains the changes to the format of the hard_limit audit
message it is dependent on modifications to the ml-cpp backend to
send additional data fields in the model size stats message. These
changes will follow in a subsequent PR. It is worth noting that this PR
must be merged prior to the ml-cpp one, to keep CI tests happy.
This change replaces the extremely unfriendly message
"Number of messages analyzed must be positive" in the
case where the sample lines were incorrectly grouped
into just one message to an error that more helpfully
explains the likely root cause of the problem.
The run task is supposed to run elasticsearch with the given plugin or

* [ML] Refactor NativeStorageProvider to enable reuse
Moves `NativeStorageProvider` as a machine learning component
so that it can be reused for other job types. Also, we now
pass the persistent task description as unique identifier which
avoids conflicts between jobs of different type but with same ids.
* Adding nativeStorageProvider as component
Since `TransportForecastJobAction` is expected to get injected a `NativeStorageProvider` class, we need to make sure that it is a constructed component, as it does not have a zero parametered, public ctor.
The date_histogram internally converts obsolete timezones (such as
"Canada/Mountain") into their modern equivalent ("America/Edmonton").
But rollup just stored the TZ as provided by the user.
When checking the TZ for query validation we used a string comparison,
which would fail due to the date_histo's upgrading behavior.
Instead, we should convert both to a TimeZone object and check if their
rules are compatible.
Values higher than 100% are now allowed to accommodate use
cases where swapping has been determined to be acceptable.
Anomaly detector jobs only use their full model memory
during background persistence, and this is deliberately
staggered, so with large numbers of jobs few will generally
be persisting state at the same time. Settings higher than
available memory are only recommended for OEM type
situations where a wrapper tightly controls the types of
jobs that can be created, and each job alone is considerably
smaller than what each node can handle.

The invalid license enforced is exposed to the cluster state update
thread (via the license state listener) before the constructor has
finished. This violates the JLS for safe publication of an object, and
means there is a concurrency bug lurking here. This commit addresses
this by avoiding publication of the invalid license enforcer before the
constructor has returned.
This change adds information about which UI path

* ml_module_auditbeat_process_docker
* ml_module_auditbeat_process_hosts
* ml_module_nginx_access
* ml_module_sample

Ensure that there is at least a 1s delay between the time that state
is persisted by each of the two jobs in the test.
Model snapshot IDs use the current time in epoch seconds to

If multiple jobs are created together and the anomaly
results index does not exist then some of the jobs could
fail to update the mappings of the results index. This
lead them to fail to write their results correctly later.
Although this scenario sounds rare, it is exactly what
happens if the user creates their first jobs using the
Nginx module in the ML UI.
This change fixes the problem by updating the mappings
of the results index if it is found to exist during a
creation attempt.

1. Makes the per-node setting xpack.ml.max_open_jobs
into a cluster-wide dynamic setting
2. Changes the job node selection to continue to use the
per-node attributes storing the maximum number of open
jobs if any node in the cluster is older than 7.1, and
use the dynamic cluster-wide setting if all nodes are on
7.1 or later
3. Changes the docs to reflect this
4. Changes the thread pools for native process communication
from fixed size to scaling, to support the dynamic nature
of xpack.ml.max_open_jobs
5. Renames the autodetect thread pool to the job comms

The assertBusy() that waits the default 10 seconds for a
datafeed to complete very occasionally times out on slow
machines. This commit increases the timeout to 60 seconds.
It will almost never actually take this long, but it's
better to have a timeout that will prevent time being
wasted looking at spurious test failures.
This test failed once in a very long time with the assertion
that there is no document for the `non_existing_job` in the
state index. I could not see how that is possible and I cannot
reproduce. With this commit the failure message will reveal
some examples of the left behind docs which might shed a light
about what could go wrong.
The ML memory tracker does searches against ML results
and config indices. These searches can be asynchronous,
and if they are running while the node is closing then
they can cause problems for other components.
This change adds a stop() method to the MlMemoryTracker
that waits for in-flight searches to complete. Once
stop() has returned the MlMemoryTracker will not kick
off any new searches.
The MlLifeCycleService now calls MlMemoryTracker.stop()
before stopping stopping the node.
Fixes#37117
These two changes are interlinked.
Before this change unsetting ML upgrade mode would wait for all
datafeeds to be assigned and not waiting for their corresponding
jobs to initialise. However, this could be inappropriate, if
there was a reason other that upgrade mode why one job was unable
to be assigned or slow to start up. Unsetting of upgrade mode
would hang in this case.
This change relaxes the condition for considering upgrade mode to
be unset to simply that an assignment attempt has been made for
each ML persistent task that did not fail because upgrade mode
was enabled. Thus after unsetting upgrade mode there is no
guarantee that every ML persistent task is assigned, just that
each is not unassigned due to upgrade mode.
In order to make setting upgrade mode work immediately after
unsetting upgrade mode it was then also necessary to make it
possible to stop a datafeed that was not assigned. There was
no particularly good reason why this was not allowed in the past.
It is trivial to stop an unassigned datafeed because it just
involves removing the persistent task.
The .ml-annotations index is created asynchronously when
some other ML index exists. This can interfere with the
post-test index deletion, as the .ml-annotations index
can be created after all other indices have been deleted.
This change adds an ML specific post-test cleanup step
that runs before the main cleanup and:
1. Checks if any ML indices exist
2. If so, waits for the .ml-annotations index to exist
3. Deletes the other ML indices found in step 1.
4. Calls the super class cleanup
This means that by the time the main post-test index
cleanup code runs:
1. The only ML index it has to delete will be the
.ml-annotations index
2. No other ML indices will exist that could trigger
recreation of the .ml-annotations index

Elasticsearch has long [supported](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html#index-versioning) compare and set (a.k.a optimistic concurrency control) operations using internal document versioning. Sadly that approach is flawed and can sometime do the wrong thing. Here's the relevant excerpt from the resiliency status page:
> When a primary has been partitioned away from the cluster there is a short period of time until it detects this. During that time it will continue indexing writes locally, thereby updating document versions. When it tries to replicate the operation, however, it will discover that it is partitioned away. It won’t acknowledge the write and will wait until the partition is resolved to negotiate with the master on how to proceed. The master will decide to either fail any replicas which failed to index the operations on the primary or tell the primary that it has to step down because a new primary has been chosen in the meantime. Since the old primary has already written documents, clients may already have read from the old primary before it shuts itself down. The version numbers of these reads may not be unique if the new primary has already accepted writes for the same document
We recently [introduced](https://www.elastic.co/guide/en/elasticsearch/reference/6.x/optimistic-concurrency-control.html) a new sequence number based approach that doesn't suffer from this dirty reads problem.
This commit removes support for internal versioning as a concurrency control mechanism in favor of the sequence number approach.

With this change we no longer support pluggable discovery implementations. No
known implementations of `DiscoveryPlugin` actually override this method, so in
practice this should have no effect on the wider world. However, we were using

no longer need a separate discovery type for tests as we no longer need to
customise its behaviour.

X-Pack security supports built-in authentication service
`token-service` that allows access tokens to be used to
access Elasticsearch without using Basic authentication.
The tokens are generated by `token-service` based on
OAuth2 spec. The access token is a short-lived token
(defaults to 20m) and refresh token with a lifetime of 24 hours,
making them unsuitable for long-lived or recurring tasks where
the system might go offline thereby failing refresh of tokens.
This commit introduces a built-in authentication service
`api-key-service` that adds support for long-lived tokens aka API
keys to access Elasticsearch. The `api-key-service` is consulted
after `token-service` in the authentication chain. By default,
if TLS is enabled then `api-key-service` is also enabled.
The service can be disabled using the configuration setting.
The API keys:-
- by default do not have an expiration but expiration can be
configured where the API keys need to be expired after a
certain amount of time.
- when generated will keep authentication information of the user that
generated them.
- can be defined with a role describing the privileges for accessing
Elasticsearch and will be limited by the role of the user that
generated them
- can be invalidated via invalidation API
- information can be retrieved via a get API
- that have been expired or invalidated will be retained for 1 week
before being deleted. The expired API keys remover task handles this.
Following are the API key management APIs:-
1. Create API Key - `PUT/POST /_security/api_key`
2. Get API key(s) - `GET /_security/api_key`
3. Invalidate API Key(s) `DELETE /_security/api_key`
The API keys can be used to access Elasticsearch using `Authorization`
header, where the auth scheme is `ApiKey` and the credentials, is the
base64 encoding of API key Id and API key separated by a colon.
Example:-
```
curl -H "Authorization: ApiKey YXBpLWtleS1pZDphcGkta2V5" http://localhost:9200/_cluster/health
```

In 7.x Java timestamp formats are the default timestamp format and
there is no need to prefix them with "8". (The "8" prefix was used

This change removes the "8" prefixes from timestamp formats in the
output of the ML file structure finder.
Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a

This is a continuation of #28667, #36137 and also fixes#37708.
Doc-value fields now return a value that is based on the mappings rather than
the script implementation by default.
This deprecates the special `use_field_mapping` docvalue format which was added

We have read and write aliases for the ML results indices. However,
the job still had methods that purported to reliably return the name
of the concrete results index being used by the job. After reindexing
prior to upgrade to 7.x this will be wrong, so the method has been
renamed and the comments made more explicit to say the returned index
name may not be the actual concrete index name for the lifetime of the
job. Additionally, the selection of indices when deleting the job
has been changed so that it works regardless of concrete index names.
All these changes are nice-to-have for 6.7 and 7.0, but will become
critical if we add rolling results indices in the 7.x release stream
as 6.7 and 7.0 nodes may have to operate in a mixed version cluster
that includes a version that can roll results indices.
The ML file structure finder has always reported both Joda
and Java time format strings. This change makes the Java time
format strings the ones that are incorporated into mappings
and ingest pipeline definitions.
The BWC syntax of prepending "8" to these formats is used.
This will need to be removed once Java time format strings
become the default in Elasticsearch.
This commit also removes direct imports of Joda classes in the
structure finder unit tests. Instead the core Joda BWC class
is used.
* Remove empty statements
There are a couple of instances of undocumented empty statements all across the
code base. While they are mostly harmless, they make the code hard to read and
are potentially error-prone. Removing most of these instances and marking blocks

* Change test, slightly more verbose but less confusing
When upgrading from 5.4 to 5.5 to 6.7 (inclusive) it was
necessary to ensure there was a mapping for type "doc" on
the ML state index before opening a job. This was because
5.4 created a multi-type ML state index.
In version 7.x we can be sure that any such 5.4 index is no
longer in use. It would have had to be reindexed into the
6.x index format prior to the upgrade to version 7.x.
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.

The ML subproject of xpack has a cache for the cpp artifact snapshots
which is checked on each build. The cache is outside of the build dir so
that it is not wiped on a typical clean, as the artifacts can be large

wipe the cache dir, as over time the size of the directory can become
bloated.
This is a continuation of #28667 and has as goal to convert all executors to propagate errors to the

We make sure to specify include_type_name=true during xContent parsing,

for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.
This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.

This is a reinforcement of #37227. It turns out that
persistent tasks are not made stale if the node they
were running on is restarted and the master node does
not notice this. The main scenario where this happens
is when minimum master nodes is the same as the number
of nodes in the cluster, so the cluster cannot elect a
master node when any node is restarted.
When an ML node restarts we need the datafeeds for any
jobs that were running on that node to not just wait
until the jobs are allocated, but to wait for the
autodetect process of the job to start up. In the case
of reassignment of the job persistent task this was
dealt with by the stale status test. But in the case
where a node restarts but its persistent tasks are not
reassigned we need a deeper test.
Fixes#36810
Added warnings checks to existing tests
Added “defaultTypeIfNull” to DocWriteRequest interface so that Bulk requests can override a null choice of document type with any global custom choice.
Related to #35190
Jobs created in version 6.1 or earlier can have a
null model_memory_limit. If these are parsed from
cluster state following a full cluster restart then
we replace the null with 4096mb to make the meaning
explicit. But if such jobs are streamed from an
old node in a mixed version cluster this does not
happen. Therefore we need to account for the
possibility of a null model_memory_limit in the ML
memory tracker.

We already had logic to stop datafeeds running against
jobs that were OPENING, but a job that relocates from
one node to another while OPENED stays OPENED, and this
could cause the datafeed to fail when it sent data to
the OPENED job on its new node before it had a
corresponding autodetect process.
This change extends the check to stop datafeeds running
when their job is OPENING _or_ stale (i.e. has not had
its status reset since relocating to a different node).
Relates #36810
When a 6.1-6.3 job is opened in a later version
we increase the model memory limit by 30% if it's
below 0.5GB. The migration of jobs from cluster
state to the config index changes the job version,
so we need to also do this uplift as part of that
config migration.

This is a follow-up of #36702 / #36698
... MlDistributedFailureIT.testLoseDedicatedMasterNode.
An intermittent failure has been observed in
`MlDistributedFailureIT. testLoseDedicatedMasterNode`.
The test launches a cluster comprised by a dedicated master node
and a data and ML node. It creates a job and datafeed and starts them.
It then shuts down and restarts the master node. Finally, the test asserts
that the two tasks have been reassigned within 10s.
The intermittent failure is due to the assertions that the tasks have been
reassigned failing. Investigating the failure revealed that the `assertBusy`
that performs that assertion times out. Furthermore, it appears that the
job task is not reassigned because the memory tracking info is stale.
Memory tracking info is refreshed asynchronously when a job is attempted
to be reassigned. Tasks are attempted to be reassigned either due to a relevant
cluster state change or periodically. The periodic interval is controlled by a cluster
setting called `cluster.persistent_tasks.allocation.recheck_interval` and defaults to 30s.
What seems to be happening in this test is that if all cluster state changes after the
master node is restarted come through before the async memory info refresh completes,
then the job might take up to 30s until it is attempted to reassigned. Thus the `assertBusy`
times out.
This commit changes the test to reduce the periodic check that reassigns persistent
tasks to `200ms`. If the above theory is correct, this should eradicate those failures.
Closes#36760

* Do not resolve addresses in remote connection info (#36671)
The remote connection info API leads to resolving addresses of seed

resolve, we would not display any remote connection info. Yet, a
hostname not resolving can happen across remote clusters, especially in
the modern world of cloud services with dynamically chaning
IPs. Instead, the remote connection info API should be providing the
configured seed nodes. This commit changes the remote connection info to
display the configured seed nodes, avoiding a hostname resolution. Note
that care was taken to preserve backwards compatibility with previous
versions that expect the remote connection info to serialize a transport
address instead of a string representing the hostname.

This creates consistency in the casting model that did not previously exist.

* [Geo] Integrate Lucene's LatLonShape (BKD Backed GeoShapes) as default `geo_shape` indexing approach (#35320)
This commit exposes lucene's LatLonShape field as the

indexing approach, simply set "type" : "geo_shape" in
the mappings without setting any of the strategy, precision,
tree_levels, or distance_error_pct parameters. Note the
following when using the new indexing approach:
* geo_shape query does not support querying by
MULTIPOINT.
* LINESTRING and MULTILINESTRING queries do not
yet support WITHIN relation.
* CONTAINS relation is not yet supported.
The tree, precision, tree_levels, distance_error_pct,
and points_only parameters are deprecated.

* ingest: support default pipelines + bulk upserts (#36618)
This commit adds support to enable bulk upserts to use an index's
default pipeline. Bulk upsert, doc_as_upsert, and script_as_upsert
are all supported.
However, bulk script_as_upsert has slightly surprising behavior since
the pipeline is executed _before_ the script is evaluated. This means
that the pipeline only has access the data found in the upsert field
of the script_as_upsert. The non-bulk script_as_upsert (existing behavior)
runs the pipeline _after_ the script is executed. This commit
does _not_ attempt to consolidate the bulk and non-bulk behavior for
script_as_upsert.
This commit also adds additional testing for the non-bulk behavior,
which remains unchanged with this commit.

* Add raw sort values to SearchSortValues transport serialization (#36617)
In order for CCS alternate execution mode (see #32125) to be able to do the final reduction step on the CCS coordinating node, we need to serialize additional info in the transport layer as part of each `SearchHit`. Sort values are already present but they are formatted according to the provided `DocValueFormat` provided. The CCS node needs to be able to reconstruct the lucene `FieldDoc` to include in the `TopFieldDocs` and `CollapseTopFieldDocs` which will feed the `mergeTopDocs` method used to reduce multiple search responses (one per cluster) into one.
This commit adds such information to the `SearchSortValues` and exposes it through a new getter method added to `SearchHit` for retrieval. This info is only serialized at transport and never printed out at REST.
* Watcher: Ensure all internal search requests count hits (#36697)

* Ensure MapperService#getAllMetaFields elements order is deterministic (#36739)
MapperService#getAllMetaFields returns an array, which is created out of
an `ObjectHashSet`. Such set does not guarantee deterministic hash
ordering. The array returned by its toArray may be sorted differently
at each run. This caused some repeatability issues in our tests (see #29080)
as we pick random fields from the array of possible metadata fields,
but that won't be repeatable if the input array is sorted differently at
every run. Once setting the tests seed, hppc picks that up and the sorting is
deterministic, but failures don't repeat with the seed that gets printed out
originally (as a seed was not originally set).
See also https://issues.carrot2.org/projects/HPPC/issues/HPPC-173.
With this commit, we simply create a static sorted array that is used for
`getAllMetaFields`. The change is in production code but really affects
only testing as the only production usage of this method was to iterate
through all values when parsing fields in the high-level REST client code.
Anyways, this seems like a good change as returning an array would imply
that it's deterministically sorted.

The results iterator is consuming and closing the results stream
once it is done. It seems this should not be the responsibility
of the results iterator. It stops the iterator from being reusable

This commit is moving the consuming and closing of the results stream
into the autodetect result processor.
This commit moves back to use explicit dependsOn for test tasks on

check directly.
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.

Today when ESIntegTestCase starts some nodes it writes out the unicast hosts
files each time a node starts its transport service. This does mean that a
number of nodes can start and perform their first pinging round without any
unicast hosts which, if the timing is unlucky and a lot of nodes are all
started at the same time, can lead to a split brain as in #35052.
Prior to #33554 this was unlikely to happen since the MockUncasedHostsProvider
would always have yielded the existing hosts, so the timing would have to have
been implausibly unlucky. Since #33554, however, it's more likely because the
race occurs between the start of the first round of pinging and the writing of
the unicast hosts file. It is realistic that new nodes will be configured with
the existing nodes from startup, so this change reinstates that behaviour.
Closes#35052.
Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.
This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.
Sometimes the cluster forming here will split-brain when it grows up to 5
nodes. This could be a timing issue or could be something going wrong in
discovery, so this asks for more logs. Relates #35052
The file structure finder endpoint can find the NDJSON
(newline-delimited JSON) file format, but called it
`json`. This change renames the `format` for this file
structure to `ndjson`, which is more precise and will
hopefully avoid confusion.
`AbstractComponent` is trouble because its name implies that
*everything* should extend from it. It *is* useful, but maybe too
broadly useful. The things it offers access too, the `Settings` instance
for the entire server and a logger are nice to have around, but not
really needed *everywhere*. The `Settings` instance especially adds a
fair bit of ceremony to testing without any value.
This removes the `nodeName` method from `AbstractComponent` so it is
more clear where we actually need the node name.
We currently have two different native processes:
autodetect & normalizer. There are plans for introducing
a new process. All these share many things in common.
This commit refactors the processes to extend an
`AbstractNativeProcess` class that encapsulates those
commonalities with the purpose of reusing the code
for new processes in the future.
This change ensures the `message` field is always included
in the `field_stats` for the semi-structured text log file
file structure. Previously it was not, as it will almost
certainly contain all distinct values. However, for
consistency in the UI it's useful to include it.
After discussing on the team's FixItFriday, we concluded that
static final instance variables that are mutable should be lowercased.
Historically, DeprecationLogger was uppercased more frequently than lowercased.
With this change, we apply the common test config automatically to all
newly created tasks instead of opting in specifically.
For plugin authors using the plugin externally this means that the
configuration will be applied to their RandomizedTestingTasks as well.
The purpose of the task is to simplify setup and make it easier to
change projects that use the `test` task but actually run integration
tests to use a task called `integTest` for clarity, but also because
we may want to configure and run them differently.
E.x. using different levels of concurrency.
#33708 introduced a strict deprecation mode that makes a REST request

This change adds the strict deprecation mode into the REST integration
tests, and makes the tests fail if a deprecated feature is used. Also
any test using a deprecated feature has been modified to pass the build.
The YAML integration tests already analyzed HTTP warnings so they do
not use this mode, keeping their "expected vs actual" behavior.
All of the tests in PainlessDomainSplitIT have an awaitsfix, which
causes the build to fail since no tests are run. This adds an empty
test to get the build going again.

In some of our X-Pack REST tests we have to wait for pending tasks to
complete. We are now needing this functionality in ESRestTestCase for
the docs tests where we run against X-Pack features. This commit moves
the helper method that we have in X-Pack to ESRestTestCase, and removes
duplicate logic from waiting for rollup tasks to complete.
The setting that reduces the disk space requirement
for the forecasting integration tests was accidentally
removed in #31757 when files were moved around. This
change simply adds back the setting that existed before
that.
This commit moves the definition of domainSplit into java and exposes it
as a painless whitelist extension. The method also no longer needs
params, and version which ignores params is added and deprecated.
The ingest pipeline that is produced is very simple. It
contains a grok processor if the format is semi-structured
text, a date processor if the format contains a timestamp,
and a remove processor if required to remove the interim
timestamp field parsed out of semi-structured text.
Eventually the UI should offer the option to customize the
pipeline with additional processors to perform other data
preparation steps before ingesting data to an index.
In ccb9ab5717 we changed how we deal with time
fields to support the `DateTime`-format fields added in 6.0, but dropped
support for pre-6.x `Long`-format fields. This change reinstates this support
for cases where pre-6.x data is made available to ML (e.g. in a mixed-version
CCS setup or after an upgrade).
This changes the delete job API by adding
the choice to delete a job asynchronously.
The commit adds a `wait_for_completion` parameter
to the delete job request. When set to `false`,
the action returns immediately and the response
contains the task id.
This also changes the handling of subsequent
delete requests for a job that is already being
deleted. It now uses the task framework to check
if the job is being deleted instead of the cluster
state. This is a beneficial for it is going to also
be working once the job configs are moved out of the
cluster state and into an index. Also, force delete
requests that are waiting for the job to be deleted
will not proceed with the deletion if the first task
fails. This will prevent overloading the cluster. Instead,
the failure is communicated better via notifications
so that the user may retry.
Finally, this makes the `deleting` property of the job
visible (also it was renamed from `deleted`). This allows
a client to render a deleting job differently.
Closes#32836
This change fixes a potential deadlock problem in the unit
test introduced in #34117.
It also removes a piece of debug code and corrects a docs
formatting problem that were both added in that same PR.
This can be used to restrict the amount of CPU a single
structure finder request can use.
The timeout is not implemented precisely, so requests
may run for slightly longer than the timeout before
aborting.
The default is 25 seconds, which is a little below
Kibana's default timeout of 30 seconds for calls to
Elasticsearch APIs.
This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
[ML] Modify thresholds for normalization triggers
The (arbitrary) threshold factors used to judge if scores have
changed significantly enough to trigger a look-back renormalization have
been changed to values that reduce the frequency of such
renormalizations.
Added a clause to treat changes in scores as a 'big change' if it would
result in a change of severity reported in the UI.
Also altered the clause affecting small scores so that a change should
be considered big if scores have changed by at least 1.5.

Previously the timestamp_formats field in the response
from the find_file_structure endpoint contained Joda
timestamp formats. This change makes that clear by
renaming the field to joda_timestamp_formats, and also
adds a java_timestamp_formats field containing the
equivalent Java time format strings.
* Make certain ML node settings dynamic (#33565)
* Changing to pull in updating settings and pass to constructor
* adding note about only newly opened jobs getting updated value
Previously numeric values in the field_stats created by the
find_file_structure endpoint were always output with a
decimal point. This looked unfriendly and unnatural for
fields that clearly store integer values. This change
converts integer values to type Integer before output in
the file structure field stats.
This change adds the OneStatementPerLineCheck to our checkstyle precommit
checks. This rule restricts the number of statements per line to one. The
resoning behind this is that it is very difficult to read multiple statements on
one line. People seem to mostly use it in short lambdas and switch statements in
our code base, but just going through the changes already uncovered some actual
problems in randomization in test code, so I think its worth it.
The job deletion logic was scattered around a few places:
the transport action, the job manager and the deletion task.
Overloading the task with deletion logic also meant extra
dependencies in the core package which should be unnecessary.
This commit consolidates all this logic into the transport action
and replaces the deletion task with a plain one that needs not be
aware of deletion logic.
We currently special-case SynonymFilterFactory and SynonymGraphFilterFactory, which need to
know their predecessors in the analysis chain in order to correctly analyze their synonym lists. This
special-casing doesn't work with Referring filter factories, such as the Multiplexer or Conditional
filters. We also have a number of filters (eg the Multiplexer) that will break synonyms when they
appear before them in a chain, because they produce multiple tokens at the same position.
This commit adds two methods to the TokenFilterFactory interface.
* `getChainAwareTokenFilterFactory()` allows a filter factory to rewrite itself against its preceding
filter chain, or to resolve references to other filters. It replaces `ReferringFilterFactory` and
`CustomAnalyzerProvider.checkAndApplySynonymFilter`, and by default returns `this`.
* `getSynonymFilter()` defines whether or not a filter should be applied when building a synonym
list `Analyzer`. By default it returns `true`.
Fixes#33609
This change modifies the file structure detection functionality
such that some of the decisions can be overridden with user
supplied values.
The fields that can be overridden are:
- charset
- format
- has_header_row
- column_names
- delimiter
- quote
- should_trim_fields
- grok_pattern
- timestamp_field
- timestamp_format
If an override makes finding the file structure impossible then
the endpoint will return an exception.
This change addresses some issues regarding thread safety around
updates and method calls on the XPackLicenseState object. There exists
a possibility that there could be a concurrent update to the
XPackLicenseState when there is a scheduled check to see if the license
is expired and a cluster state update. In order to address this, the
update method now has a synchronized block where member variables are
updated. Each method that reads these variables is now also
synchronized.
Along with the above change, there was a consistency issue around
security calls to the license state. The majority of security checks
make two calls to the license state, which could result in incorrect
behavior due to the checks being made against different license states.
The majority of this behavior was introduced for 6.3 with the inclusion
of x-pack in the default distribution. In order to resolve the majority
of these cases, the `isSecurityEnabled` method is no longer public and
the logic is also included in individual methods about security such as
`isAuthAllowed`. There were a few cases where this did not remove
multiple calls on the license state, so a new method has been added
which creates a copy of the current license state that will not change.
Callers can use this copy of the license state to make decisions based
on a consistent view of the license state.
This change tightens up the meaning of the "input_fields" field
in the file structure finder output. Previously it was permitted
but not calculated for JSON and XML files. Following this change
the field is called "column_names" and is only permitted for
delimited files.
Additionally the way the column names are set for headerless
delimited files is refactored to encapsulate the way they're
named to one line of the code rather than having the same
logic in two places.
When requesting job stats for `_all`, all ES tasks are accepted
resulting to loads of cluster traffic and a memory overhead.
This commit correctly filters out non ML job tasks.
Closes#33515
This commit ensures that we bootstrap a new history_uuid when force
allocating a stale primary. A stale primary should never be the source
of an operation-based recovery to another shard which exists before the
forced-allocation.
Closes#26712
This endpoint accepts an arbitrary file in the request body and
attempts to determine the structure. If successful it also
proposes mappings that could be used when indexing the file's
contents, and calculates simple statistics for each of the fields
that are useful in the data preparation step prior to configuring
machine learning jobs.
This change collapses all metrics aggregations classes into a single package `org.elasticsearch.aggregations.metrics`.
It also restricts the visibility of some classes (aggregators and factories) that should not be used outside of the package.
Relates #22868
Many files supplied to the upcoming ML data preparation
functionality will not be "log" files. For example,
CSV files are generally not "log" files. Therefore it
makes sense to rename library that determines the
structure of these files.
Although "file structure" could be considered too broad,
as the library currently only works with a few text
formats, in the future it may be extended to work with
more formats.
The log structure endpoint will return these in addition to
pure structure information so that it can be used to drive
pre-import data visualizer functionality.
The statistics for every field are count, cardinality
(distinct count) and top hits (most common values). Extra
statistics are calculated if the field is numeric: min, max,
mean and median.
This is not changing the behaviour as when the sort field was set
to `influencer_score` the secondary sort would be used and that
was using the `record_score` at the highest priority.
1. The TOMCAT_DATESTAMP format needs to be checked before
TIMESTAMP_ISO8601, otherwise TIMESTAMP_ISO8601 will
match the start of the Tomcat datestamp.
2. Exclude more characters before and after numbers. For
example, in 1.2.3 we don't want to match 1.2 as a float.

In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `x-pack/qa/ml-basic-multi-node` project to use
the new versions.
This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.
As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:
```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```
You can instead use the much more normal:
```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `x-pack/qa/audit-tests`,
`x-pack/qa/ml-disabled`, and `x-pack/qa/multi-node` projects to use the
new versions.
This commit moves the ML QA tests to be a sub-project of ML. The purpose
of this refactoring is to enable ML developers to run
:x-pack:plugin:ml:check and run the vast majority of a ML tests with a
single command (this still does not contain the ML REST tests, nor the
upgrade tests). This simplifies local development for faster iteration.
This commit implements licensing for CCR. CCR will require a platinum
license, and administrative endpoints will be disabled when a license is
non-compliant.
Machine learning has baked a remote license checker for use in checking
license compatibility of a remote license. This remote license checker
has general usage for any feature that relies on a remote cluster. For
example, cross-cluster replication will pull changes from a remote
cluster and require that the local and remote clusters have platinum
licenses. This commit generalizes the remote cluster license check for
use in cross-cluster replication.
* ML: fix updating opened jobs scheduled events (#31651)
* Adding UpdateParamsTests license header
* Adding integration test and addressing PR comments
* addressing test and job names
This change adds a library to ML that can be used to deduce a log
file's structure given only a sample of the log file.
Eventually this will be used to add an endpoint to ML to make the
functionality available to end users, but this will follow in a
separate change.
The functionality is split into a library so that it can also be
used by a command line tool without requiring the command line
tool to include all server code.
This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
[ML] Removing old per-partition normalization code
Per-partition normalization is an old, undocumented feature that was
never used by clients. It has been superseded by per-partition maximum
scoring.
To maintain communication compatibility with nodes prior to 6.5 it is
necessary to maintain/cope with the old wire format
Added infrastructure to push through the 'person name field value' to
the normalizer process. This is required by the normalizer to retrieve
the maximum scores for individual partitions.
* Clear Job#finished_time when it is opened (#32605)
* not returning failure when Job#finished_time is not reset
* Changing error log string and source string
The upcoming ML log structure finder functionality will use these

being used elsewhere in Elasticsearch. This is especially true
with icu4j, which is pretty big.
This commit removes the never released multiple_bucket_spans
configuration parameter. This is now replaced with the new
multibucket feature that requires no configuration.
* Upgrade to `4.1.28` since the problem reported in #32487 is a bug in Netty itself (see https://github.com/netty/netty/issues/7337)
* Fixed other leaks in test code that now showed up due to fixes improvements in leak reporting in the newer version
* Needed to extend permissions for netty common package because it now sets a classloader at runtime after changes in 63bae0956a
* Adjusted forbidden APIs check accordingly
* Closes#32487
Previously we had two patterns for naming of strict
and lenient parsers.
Some classes had CONFIG_PARSER and METADATA_PARSER,
and used an enum to pass the parser type to nested
parsers.
Other classes had STRICT_PARSER and LENIENT_PARSER
and used ternary operators to pass the parser type
to nested parsers.
This change makes all ML classes use the second of
the patterns described above.
Removing some dead code or supressing warnings where apropriate. Most of the
time the variable tested for null is dereferenced earlier or never used before.
This commit introduces "Application Privileges" to the X-Pack security
model.
Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.
Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.
Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
objects
- a new "global" element on role definition to provide cluster object
level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
`kibana_system` roles to use and manage application privileges
Closes#29820Closes#31559
This bundles the x-pack:protocol project into the x-pack:plugin:core
project because we'd like folks to consider it an implementation detail
of our build rather than a separate artifact to be managed and depended
on. It is now bundled into both x-pack:plugin:core and
client:rest-high-level. To make this work I had to fix a few things.
Firstly, I had to make PluginBuildPlugin work with the shadow plugin.
In that case we have to bundle only the `shadow` dependencies and the
shadow jar.
Secondly, every reference to x-pack:plugin:core has to use the `shadow`
configuration. Without that the reference is missing all of the
un-shadowed dependencies. I tried to make it so that applying the shadow
plugin automatically redefines the `default` configuration to mirror the
`shadow` configuration which would allow us to use bare project references
to the x-pack:plugin:core project but I couldn't make it work. It'd *look*
like it works but then fail for transitive dependencies anyway. I think
it is still a good thing to do but I don't have the willpower to do it
now.
Finally, I had to fix an issue where Eclipse and IntelliJ didn't properly
reference shadowed transitive dependencies. Neither IDE supports shadowing
natively so they have to reference the shadowed projects. We fix this by
detecting `shadow` dependencies when in "Intellij mode" or "Eclipse mode"
and adding `runtime` dependencies to the same target. This convinces
IntelliJ and Eclipse to play nice.
The initial decision to use async durability was made a long time ago
for performance reasons. That argument no longer applies and we
prefer the safety of request durability.
Prior to 6.3 a trial license default to security enabled. Since 6.3
they default to security disabled. If a cluster is upgraded from <6.3
to >6.3, then we detect this and mimic the old behaviour with respect
to security.
The ML config classes will shortly be moved to the X-Pack protocol
library to allow the ML APIs to be moved to the high level REST
client. Dependencies on server functionality should be removed
from the config classes before this is done.
This change is entirely about moving code between packages. It
does not add or remove any functionality or tests.
When an ML job cannot be allocated to a node the exception
contained an explanation of why the job couldn't be
allocated to each node in the cluster. For large clusters
this was not particularly easy to read and made the error
displayed in the UI look very scary.
This commit changes the structure of the error to an outer
ElasticsearchException with a high level message and an
inner IllegalStateException containing the detailed
explanation. Because the definition of root cause is the
innermost ElasticsearchException the detailed explanation
will not be the root cause (which is what Kibana displays).
Fixes#29950
Originally I put the X-Pack info object into the top level rest client
object. I did that because we thought we'd like to squash `xpack` from
the name of the X-Pack APIs now that it is part of the default
distribution. We still kind of want to do that, but at least for now we
feel like it is better to keep the high level rest client aligned with
the other language clients like C# and Python. This shifts the X-Pack
info API to align with its json spec file.
Relates to #31870
This is the first x-pack API we're adding to the high level REST client
so there is a lot to talk about here!
= Open source
The *client* for these APIs is open source. We're taking the previously
Elastic licensed files used for the `Request` and `Response` objects and
relicensing them under the Apache 2 license.
The implementation of these features is staying under the Elastic
license. This lines up with how the rest of the Elasticsearch language
clients work.
= Location of the new files
We're moving all of the `Request` and `Response` objects that we're
relicensing to the `x-pack/protocol` directory. We're adding a copy of
the Apache 2 license to the root fo the `x-pack/protocol` directory to
line up with the language in the root `LICENSE.txt` file. All files in
this directory will have the Apache 2 license header as well. We don't
want there to be any confusion. Even though the files are under the
`x-pack` directory, they are Apache 2 licensed.
We chose this particular directory layout because it keeps the X-Pack
stuff together and easier to think about.
= Location of the API in the REST client
We've been following the layout of the rest-api-spec files for other
APIs and we plan to do this for the X-Pack APIs with one exception:
we're dropping the `xpack` from the name of most of the APIs. So
`xpack.graph.explore` will become `graph().explore()` and
`xpack.license.get` will become `license().get()`.
`xpack.info` and `xpack.usage` are special here though because they
don't belong to any proper category. For now I'm just calling
`xpack.info` `xPackInfo()` and intend to call usage `xPackUsage` though
I'm not convinced that this is the final name for them. But it does get
us started.
= Jars, jars everywhere!
This change makes the `xpack:protocol` project a `compile` scoped
dependency of the `x-pack:plugin:core` and `client:rest-high-level`
projects. I intend to keep it a compile scoped dependency of
`x-pack:plugin:core` but I intend to bundle the contents of the protocol
jar into the `client:rest-high-level` jar in a follow up. This change
has grown large enough at this point.
In that followup I'll address javadoc issues as well.
= Breaking-Java
This breaks that transport client by a few classes around. We've
traditionally been ok with doing this to the transport client.
Job persistent tasks with stale allocation IDs used to always be
considered as OPENING jobs in the ML job node allocation decision.
However, FAILED jobs are not relocated to other nodes, which leads
to them blocking up the nodes they failed on after node restarts.
FAILED jobs should not restrict how many other jobs can open on a
node, regardless of whether they are stale or not.
Closes#31794
Job updates or changes to calendars or filters may
result into updating the job process if it has been
running. To preserve the order of updates, process
updates are queued through the UpdateJobProcessNotifier
which is only running on the master node. All actions
performing such updates must run on the master node.
However, the CRUD actions for calendars and filters
are not master node actions. They have been submitting
the updates to the UpdateJobProcessNotifier even though
it might have not been running (given the action was
run on a non-master node). When that happens, the update
never reaches the process.
This commit fixes this problem by ensuring the notifier
runs on all nodes and by ensuring the process update action
gets the resources again before updating the process
(instead of having those resources passed in the request).
This ensures that even if the order of the updates
gets messed up, the latest update will read the latest
state of those resource and the process will get back
in sync.
This leaves us with 2 types of updates:
1. updates to the job config should happen on the master
node. This is because we cannot refetch the entire job
and update it. We need to know the parts that have been changed.
2. updates to resources the job uses. Those can be handled
on non-master nodes but they should be re-fetched by the
update process action.
Closes#31803
There is at most one model size stats document per bucket, but
during lookback a job can churn through many buckets very quickly.
This can lead to many cluster state updates if established model
memory needs to be updated for a given model size stats document.
This change rate limits established model memory updates to one
per job per 5 seconds. This is done by scheduling the updates 5
seconds in the future, but replacing the value to be written if
another model size stats document is received during the waiting
period. Updating the values in arrears like this means that the
last value received will be the one associated with the job in the
long term, whereas alternative approaches such as not updating the
value if a new value was close to the old value would not.
This change adds stats about forecasts, to the jobstats api as well as xpack/_usage. The following
information is collected:
_xpack/ml/anomaly_detectors/{jobid|_all}/_stats:
- total number of forecasts
- memory statistics (mean/min/max)
- runtime statistics
- record statistics
- counts by status
_xpack/usage
- collected by job status as well as overall (_all):
- total number of forecasts
- number of jobs that have at least 1 forecast
- memory, runtime, record statistics
- counts by status
Fixes#31395
* Remove deprecation warnings to prepare for Gradle 5
Gradle replaced `project.sourceSets.main.output.classesDir` of type
`File` with `project.sourceSets.main.output.classesDirs` of type
`FileCollection`
(see [SourceSetOutput](https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/java/org/gradle/api/tasks/SourceSetOutput.java))
Build output is now stored on a per language folder.
There are a few places where we use that, here's these and how it's
fixed:
- Randomized Test execution
- look in all test folders ( pass the multi dir configuration to the
ant runner )
- DRY the task configuration by introducing `basedOn` for
`RandomizedTestingTask` DSL
- Extend the naming convention test to support passing in multiple
directories
- Fix the standalon test plugin, the dires were not passed trough,
checked with a debuger and the statement had no affect due to a
missing `=`.
Closes#30354
* Only check Java tests, PR feedback
- Name checker was ran for Groovy tests that don't adhere to the same
convections causing the check to fail
- implement PR feedback
* Replace `add` with `addAll`
This worked because the list is passed to `project.files` that does the
right thing.
* Revert "Only check Java tests, PR feedback"
This reverts commit 9bd9389875d8b88aadb50df57a45cd0d2b073241.
* Remove `basedOn` helper
* Bring some changes back
Previus revert accidentally reverted too much
* Fix negation
* add back public
* revert name check changes
* Revert "revert name check changes"
This reverts commit a2800c0b363168339ea65e2a79ec8256e5883e6d.
* Pass all dirs to name check
Only run on Java for build-tools, this is safe because it's a self test.
It needs more work before we could pass in the Groovy classes as well as
these inherit from `GroovyTestCase`
* remove self tests from name check
The self complicates the task setup and disable real checks on
build-tools.
With this change there are no more self tests, and the build-tools tests
adhere to the conventions.
The self test will be replaced by gradle test kit, thus the addition of
the Gradle plugin builder plugin.
* First test to run a Gradle build
* Add tests that replace the name check self test
* Clean up integ test base class
* Always run tests
* Align with test naming conventions
* Make integ. test case inherit from unit test case
The check requires this
* Remove `import static org.junit.Assert.*`
TransportAction currently contains 2 doExecute methods, one which takes
a the task, and one that does not. The latter is what some subclasses
implement, while the first one just calls the latter, dropping the given
task. This commit combines these methods, in favor of just always
assuming a task is present.
This adds an api to allow updating a filter:
POST _xpack/ml/filters/{filter_id}/_update
The request body may have:
- description: setting a new description
- add_items: a list of the items to add
- remove_items: a list of the items to remove
This commit also changes the PUT filter api to
error when the filter_id is already used. As
now there is an api for updating filters, the
put api should only be used to create new ones.
Also, updating a filter results into a notification
message auditing the change for every job that is
using that filter.
In #29639 we added a `format` option to doc-value fields and deprecated usage
of doc-value fields without a format so that we could migrate doc-value fields
to use the format that comes with the mappings by default. However I missed to
fix the machine-learning datafeed extractor.
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.
This commit makes it so that cluster state update tasks always run under the system context, only
restoring the original context when the listener that was provided with the task is called. A notable
exception is the clusterStatePublished(...) callback which will still run under system context,
because it's defined on the executor-level, and not the task level, and only called once for the
combined batch of tasks and can therefore not be uniquely identified with a task / thread context.
Relates #30603
This pull request removes the relationship between the state
of persistent task (as stored in the cluster state) and the status
of the task (as reported by the Task APIs and used in various
places) that have been confusing for some time (#29608).
In order to do that, a new PersistentTaskState interface is added.
This interface represents the persisted state of a persistent task.
The methods used to update the state of persistent tasks are
renamed: updatePersistentStatus() becomes updatePersistentTaskState()
and now takes a PersistentTaskState as a parameter. The
Task.Status type as been changed to PersistentTaskState in all
places were it make sense (in persistent task customs in cluster
state and all other methods that deal with the state of an allocated
persistent task).
This adds a `description` to ML filters in order
to allow users to describe their filters in a human
readable form which is also editable (filter updates
to be added shortly).
This change prevents a datafeed using cross cluster search from starting if the remote cluster
does not have x-pack installed and a sufficient license. The check is made only when starting a
datafeed.
Rules allow users to supply a detector with domain
knowledge that can improve the quality of the results.
The model detects statistically anomalous results but it
has no knowledge of the meaning of the values being modelled.
For example, a detector that performs a population analysis
over IP addresses could benefit from a list of IP addresses
that the user knows to be safe. Then anomalous results for
those IP addresses will not be created and will not affect
the quantiles either.
Another example would be a detector looking for anomalies
in the median value of CPU utilization. A user might want
to inform the detector that any results where the actual
value is less than 5 is not interesting.
This commit introduces a `custom_rules` field to the `Detector`.
A detector may have multiple rules which are combined with `or`.
A rule has 3 fields: `actions`, `scope` and `conditions`.
Actions is a list of what should happen when the rule applies.
The current options include `skip_result` and `skip_model_update`.
The default value for `actions` is the `skip_result` action.
Scope is optional and allows for applying filters on any of the
partition/over/by field. When not defined the rule applies to
all series. The `filter_id` needs to be specified to match the id
of the filter to be used. Optionally, the `filter_type` can be specified
as either `include` (default) or `exclude`. When set to `include`
the rule applies to entities that are in the filter. When set to
`exclude` the rule only applies to entities not in the filter.
There may be zero or more conditions. A condition requires `applies_to`,
`operator` and `value` to be specified. The `applies_to` value can be
either `actual`, `typical` or `diff_from_typical` and it specifies
the numerical value to which the condition applies. The `operator`
(`lt`, `lte`, `gt`, `gte`) and `value` complete the definition.
Conditions are combined with `and` and allow to specify numerical
conditions for when a rule applies.
A rule must either have a scope or one or more conditions. Finally,
a rule with scope and conditions applies when all of them apply.
This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.
ObjectParser should throw XContentParseExceptions, not IAE. A dedicated parsing
exception can includes the place where the error occurred.
Closes#30605
This commit removes the RequestBuilder generic type from Action. It was
needed to be used by the newRequest method, which in turn was used by
client.prepareExecute. Both of these methods are now removed, along with
the existing users of prepareExecute constructing the appropriate
builder directly.
This commit renames methods in the PersistentTasksService, to
make obvious that the methods send requests in order to change
the state of persistent tasks.
Relates to #29608.
ML has dedicated APIs for datafeeds and jobs yet base test classes and
some tests were relying on the cluster state for this state. This commit
removes this usage in favor of using the dedicated endpoints.
This commit adds the ability to configure how a docvalue field should be
formatted, so that it would be possible eg. to return a date field
formatted as the number of milliseconds since Epoch.
Closes#27740
Enables a rolling restart from the OSS distribution to the x-pack based distribution by preventing
x-pack code from installing custom metadata into the cluster state until all nodes are capable of
deserializing this metadata.
When doing a node restart using the test framework, the restarted node does not only use the
settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.
This change is to support rolling upgrade from a pre-6.3 default
distribution (i.e. without X-Pack) to a 6.3+ default distribution
(i.e. with X-Pack).
The ML metadata is no longer eagerly added to the cluster state
as soon as the master node has X-Pack available. Instead, it
is added when the first ML job is created.
As a result all methods that get the ML metadata need to be able
to handle the situation where there is no ML metadata in the
current cluster state. They do this by behaving as though an
empty ML metadata was present. This logic is encapsulated by
always asking for the current ML metadata using a static method
on the MlMetadata class.

diskspace and creates a subfolder for storing data outside of Lucene
indexes, but as part of the ES data paths.
Details:
- tmp storage is managed and does not allow allocation if disk space is
below a threshold (5GB at the moment)
- tmp storage is supposed to be managed by the native component but in
case this fails cleanup is provided:
- on job close
- on process crash
- after node crash, on restart
- available space is re-checked for every forecast call (the native
component has to check again before writing)
Note: The 1st path that has enough space is chosen on job open (job
close/reopen triggers a new search)
This change adds version information in case a native ML process crashes, the version is important for choosing the right symbol files when analyzing the crash. Adding the version combines all necessary information on one line.

It is possible for state documents to be
left behind in the state index. This may be
because of bugs or uncontrollable scenarios.
In any case, those documents may take up quite
some disk space when they add up. This commit
adds a step in the expired data deletion that
is part of the daily maintenance service. The
new step searches for state documents that
do not belong to any of the current jobs and
deletes them.
Closes#30551
* Refactors ClientHelper to combine header logic
This change removes all the `*ClientHelper` classes which were
repeating logic between plugins and instead adds
`ClientHelper.executeWithHeaders()` and
`ClientHelper.executeWithHeadersAsync()` methods to centralise the
logic for executing requests with stored security headers.
* Removes Watcher headers constant
This change adds a grok_pattern field to the GET categories API
output in ML. It's calculated using the regex and examples in the
categorization result, and applying a list of candidate Grok
patterns to the bits in between the tokens that are considered to
define the category.
This can currently be considered a prototype, as the Grok patterns
it produces are not optimal. However, enough people have said it
would be useful for it to be worthwhile exposing it as experimental
functionality for interested parties to try out.
This commit fixes an issue with the data diagnostics were
empty buckets are not reported even though they should. Once
a job is reopened, the diagnostics do not get initialized from
the current data counts (especially the latest record timestamp).
The result is that if the data that is sent have a time gap compared
to the previous ones, that gap is not accounted for in the empty bucket
count.
This commit fixes that by initializing the diagnostics with the current
data counts.
Closes#30080
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
closes#12792
This commit refactors the DataStreamDiagnostics class
achieving the following advantages:
- simpler code; by encapsulating the moving bucket histogram
into its own class
- better performance; by using an array to store the buckets
instead of a map
- explicit handling of gap buckets; in preparation of fixing #30080
The overall NOTICE file for the ML X-Pack module should
include the notices from the 3rd party C++ components as
well as the 3rd party Java components.
Tests need to wait for changes to the job's established memory usage to
propagate and an over enthusiastic optimisation meant jobs were updated
from stale state causing recent change to be lost.
