Adjusts the cluster cleanup routine in ESRestTestCase to clean up SLM
test cases, and optionally wait for all snapshots to be deleted.
Waiting for all snapshots to be deleted, rather than failing if any are
in progress, is necessary for tests which use SLM policies because SLM
policies may be in the process of executing when the test ends.
This change adds the support for the RankFeatureQuery in the HLRC by
providing an extra dependency on mapper-extras-client. It also removes
the dependency on lang-painless in mapper-extras which is not needed
anymore since the move of the vector field into a dedicated module.

Today we recover a replica by copying operations from the primary's translog.
However we also retain some historical operations in the index itself, as long
as soft-deletes are enabled. This commit adjusts peer recovery to use the
operations in the index for recovery rather than those in the translog, and
ensures that the replication group retains enough history for use in peer
recovery by means of retention leases.

* Fix one more import
Adds an API to clone an index. This is similar to the index split and shrink APIs, just with the
difference that the number of primary shards is kept the same. In case where the filesystem
provides hard-linking capabilities, this is a very cheap operation.
Indexing cloning can be done by running `POST my_source_index/_clone/my_target_index` and it
supports the same options as the split and shrink APIs.

This is a followup to #44350. The indexer stats used to
be persisted standalone, but now are only persisted as
part of a state-and-stats document. During the review

design, so there will never be a need for an indexer
stats object to store its transform ID as it is stored
on the enclosing document. This PR removes the indexer
stats document ID.

With the commit, we now validate the content of snapshot lifecycle policies when

* Add API to execute SLM policy on demand (#41038)
This commit adds the ability to perform a snapshot on demand for a policy. This
can be useful to take a snapshot immediately prior to performing some sort of
maintenance.
```json
PUT /_ilm/snapshot/<policy>/_execute
```
And it returns the response with the generated snapshot name:
```json
{
"snapshot_name" : "production-snap-2019.04.09-rfyv3j9qreixkdbnfuw0ug"

```
Note that this does not allow waiting for the snapshot, and the snapshot could
still fail. It *does* record this information into the cluster state similar to
a regularly trigged SLM job.

It is useful to have a record of the actions that Snapshot Lifecycle

time.
This adds the infrastructure to record SLM actions into an index that
can be queried at leisure, along with a lifecycle policy so that this
history does not grow without bound.
Additionally,
SLM automatically setting up an index + lifecycle policy leads to
`index_lifecycle` custom metadata in the cluster state, which some of
the ML tests don't know how to deal with due to setting up custom
`NamedXContentRegistry`s. Watcher would cause the same problem, but it
is already disabled (for the same reason).

Currently we loose information about whether a token list in an AnalyzeAction
response is null or an empty list, because we write a 0 value to the stream in

or not, followed by the size of the list and its content.

Rewrites how continuous data frame transforms calculates and handles buckets that require an update. Instead of storing the whole set in memory, it pages through the updates using a 2nd cursor. This lowers memory consumption and prevents problems with limits at query time (max_terms_count). The list of updates can be re-retrieved in a failure case (#43662)
The base classes for transport requests and responses currently
implement Streamable and Writeable. The writeTo method on these base
classes is implemented with an empty implementation. Not only does this
complicate subclasses to think they need to call super.writeTo, but it
also can lead to not implementing writeTo when it should have been
implemented, or extendiong one of these classes when not necessary,
since there is nothing to actually implement.
This commit removes the empty writeTo from these base classes, and fixes
subclasses to not call super and in some cases implement an empty
writeTo themselves.

Previously a data frame transform would check whether the
source index was changed every 10 seconds. Sometimes it
may be desirable for the check to be done less frequently.
This commit increases the default to 60 seconds but also
allows the frequency to be overridden by a setting in the
data frame transform config.
The rest client does not communicate over the transport protocol.
However, in the move to make all apis supported in the HLRC, some
response classes were copied with extending ActionResponse, which is
meant strictly for the transport protocol. This commit removes uses of
that base class from HLRC.
Currently we log a deprecation warning to the types removal in
RestGetIndicesAction even if the REST method is HEAD, which is used by the
indices.exists API. Since the body is empty in this case we should not need to
show the deprecation warning.
Closes#43905
In MachineLearningIT.testStopDataFrameAnalytics we call start and
then assert the state is `started`. However, if things go fast enough,
the state could have already changed to `reindexing` or `analyzing`.
The test has been failing occasionally due to the state being
`reindexing`. We fix this by simply asserting the state is either
of `started`, `reindexing` or `analyzing`.
Closes#43924
This introduces a `failed` state to which the data frame analytics
persistent task is set to when something unexpected fails. It could
be the process crashing, the results processor hitting some error,
etc. The failure message is then captured and set on the task state.
From there, it becomes available via the _stats API as `failure_reason`.
The df-analytics stop API now has a `force` boolean parameter. This allows
the user to call it for a failed task in order to reset it to `stopped` after
we have ensured the failure has been communicated to the user.
This commit also adds the analytics version in the persistent task
params as this allows us to prevent tasks to run on unsuitable nodes in
the future.

Adds the monitor_data_frame_transforms and
manage_data_frame_transforms cluster privileges to
the high level rest client.
The ALL_ARRAY variable is only used in randomized
tests at the within the Elasticsearch code, so it's
not a major problem that these cluster privileges
weren't added from the start. But since ALL_ARRAY
is public HLRC users may be using it to find out
which cluster privileges exist, so it's best that
it contains them all.
This commit adds support for multiple source indices.
In order to deal with multiple indices having different mappings,
it attempts a best-effort approach to merge the mappings assuming
there are no conflicts. In case conflicts exists an error will be
returned.
To allow users creating custom mappings for special use cases,
the destination index is now allowed to exist before the analytics
job runs. In addition, settings are no longer copied except for
the `index.number_of_shards` and `index.number_of_replicas`.
Currently changing resources (like dictionaries, synonym files etc...) of search
time analyzers is only possible by closing an index, changing the underlying
resource (e.g. synonym files) and then re-opening the index for the change to
take effect.
This PR adds a new API endpoint that allows triggering reloading of certain
analysis resources (currently token filters) that will then pick up changes in
underlying file resources. To achieve this we introduce a new type of custom
analyzer (ReloadableCustomAnalyzer) that uses a ReuseStrategy that allows
swapping out analysis components. Custom analyzers that contain filters that are
markes as "updateable" will automatically choose this implementation. This PR
also adds this capability to `synonym` token filters for use in search time
analyzers.

This merges the initial work that adds a framework for performing
machine learning analytics on data frames. The feature is currently experimental
and requires a platinum license. Note that the original commits can be
found in the `feature-ml-data-frame-analytics` branch.
A new set of APIs is added which allows the creation of data frame analytics
jobs. Configuration allows specifying different types of analysis to be performed
on a data frame. At first there is support for outlier detection.
The APIs are:
- PUT _ml/data_frame/analysis/{id}
- GET _ml/data_frame/analysis/{id}
- GET _ml/data_frame/analysis/{id}/_stats
- POST _ml/data_frame/analysis/{id}/_start
- POST _ml/data_frame/analysis/{id}/_stop
- DELETE _ml/data_frame/analysis/{id}
When a data frame analytics job is started a persistent task is created and started.
The main steps of the task are:
1. reindex the source index into the dest index
2. analyze the data through the data_frame_analyzer c++ process
3. merge the results of the process back into the destination index
In addition, an evaluation API is added which packages commonly used metrics
that provide evaluation of various analysis:
- POST _ml/data_frame/_evaluate

Kibana wants to create access_token/refresh_token pair using Token
management APIs in exchange for kerberos tickets. `client_credentials`
grant_type requires every user to have `cluster:admin/xpack/security/token/create`
cluster privilege.
This commit introduces `_kerberos` grant_type for generating `access_token`
and `refresh_token` in exchange for a valid base64 encoded kerberos ticket.
In addition, `kibana_user` role now has cluster privilege to create tokens.
This allows Kibana to create access_token/refresh_token pair in exchange for
kerberos tickets.
Note:
The lifetime from the kerberos ticket is not used in ES and so even after it expires
the access_token/refresh_token pair will be valid. Care must be taken to invalidate
such tokens using token management APIs if required.

The xpack info api currently returns native code info within each
feature. This commit deprecates retrieving that info, which is now
available directly in the ML info api.
The painless context api is internal and currently meant only for use in
generating docs. This commit moves the spec file for the api so that it
is only used by the test for this api, and not externally by any clients
building from the public rest spec.
The description field of xpack featuresets is optionally part of the
xpack info api, when using the verbose flag. However, this information
is unnecessary, as it is better left for documentation (and the existing
descriptions describe anything meaningful). This commit removes the
description field from feature sets.
Previously, a reindex request had two different size specifications in the body:
* Outer level, determining the maximum documents to process
* Inside the source element, determining the scroll/batch size.
The outer level size has now been renamed to max_docs to

deprecation warnings for using size.
Similarly, the size parameter has been renamed to max_docs for
update/delete-by-query to keep the 3 interfaces consistent.
Finally, all 3 endpoints now support max_docs in both body and URL.

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.

The existing `RequestConverters.Params` is confusing, because it wraps
an underlying request object and mutations of the `Params` object
actually mutate the `Request` that was used in the construction of the
`Params`.
This leads to a situation where we create a `RequestConverter.Params`
object, mutate it, and then it appears nothing happens to it - it
appears to be unused. What happens behind the scenes is that the Request
object is mutated when methods on `Params` are invoked. This results in
unclear, confusing code where mutating one object changes another with
no obvious connection.
This commit refactors `RequestConverters.Params` to be a simple helper
class to produce a `Map` which must be passed explicitly to a Request
object. This makes it apparent that the `Params` are actually used, and
that they have an effect on the `request` object explicit and easier to
understand.

Removing of payload in BulkRequest (#39843) had a side effect of making

RequestConvertersTests to show the error and the corresponding fix in

Fixes#41668
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

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.

Today the `_field_caps` API returns the list of indices where a field
is present only if this field has different types within the requested indices.
However if the request is an index pattern (or an alias, or both...) there
is no way to infer the indices if the response contains only fields that have
the same type in all indices. This commit changes the response to always return
the list of indices in the response. It also adds a way to retrieve unmapped field
in a specific section per field called `unmapped`. This section is created for each field
that is present in some indices but not all if the parameter `include_unmapped` is set to
true in the request (defaults to false).
In order to support empty action metadata in the first msearch item,
we need to remove support for prepending msearch request body with an
empty line, which prevents us from parsing the empty line as action
metadata for the first search item.

hamcrest has some improvements in newer versions, like FileMatchers
that make assertions regarding file exists cleaner. This commit upgrades
to the latest version of hamcrest so we can start using new and improved
matchers.
* The test fails for the retry backoff enabled case because the retry handler in the bulk processor hasn't been adjusted to account for #40866 which now might lead to an outright rejection of the request instead of its items individually
* Fixed by adding retry functionality to the top level request as well
* Also fixed the duplicate test for the HLRC that wasn't handling the non-backoff case yet the same way the non-client IT did
* closes#41324
This change adds either ToXContentObject or ToXContentFragment to classes
directly implementing ToXContent currently. This helps in reasoning about
whether those implementations output full xcontent object or just fragments.

* moved hlrc parsing tests from xpack to hlrc module and removed dependency on hlrc from xpack core
* deprecated old base test class
* added deprecated jdoc tag
* split test between xpack-core part and hlrc part
* added lang-mustache test dependency, this previously came in via
hlrc dependency.
* added hlrc dependency on a qa module
* duplicated ClusterPrivilegeName class in xpack-core, since x-pack
core no longer has a dependency on hlrc.
* replace ClusterPrivilegeName usages with string literals
* moved tests to dedicated to hlrc packages in order to remove Hlrc part from the name and make sure to use imports instead of full qualified class where possible
* remove ESTestCase. from method invocation and use method directly,
because these tests indirectly extend from ESTestCase
changed hlrc ccr request tests to use AbstractRequestTestCase base class.
This way the request classes are tested in a more realistic setting.
Note this change also adds a test dependency on xpack core module.
Similar to #39844 but then for hlrc request serialization tests.
Removed iterators from hlrc parsing tests.
Use empty xcontent registries.

Made changes to ensure that unique IDs are generated for model snapshots
used by the deleteExpiredDataTest test in the MachineLearningIT suite.
Previously a sleep of 1s was performed between jobs under the assumption
that this would be sufficient to guarantee that the timestamps used in
the composition of the snapshot IDs would be different.
The new approach is to wait on the condition that the old and new
timestamps are in fact different (to 1s resolution).
This commit fixes a problem with BWC that was brought up in #40511. A
newer version of the code was emitting a new value for an enum to an
older version, and the older version could not handle that. It caused
the response to error. The MainResponse is now relaxed, and will accept
whatever values the server expose, and holds most of them as Strings
instead of complex objects.
Fixes#40511
This adds a new `role_templates` field to role mappings that is an
alternative to the existing roles field.
These templates are evaluated at runtime to determine which roles should be
granted to a user.
For example, it is possible to specify:
"role_templates": [
{ "template":{ "source": "_user_{{username}}" } }
]
which would mean that every user is assigned to their own role based on
their username.
You may not specify both roles and role_templates in the same role
mapping.
This commit adds support for templates to the role mapping API, the role
mapping engine, the Java high level rest client, and Elasticsearch
documentation.
Due to the lack of caching in our role mapping store, it is currently
inefficient to use a large number of templated role mappings. This will be
addressed in a future change.
Backport of: #39984, #40504
It initially mentioned the type in the exception because the type used to be
required to uniquely identify a document. This is not necessary anymore given
that indices have at most one type.
The reindex family of APIs (reindex, update-by-query, delete-by-query) can
sometimes return responses that have an error status code (409 Conflict in this
case) but still have a body in the usual BulkByScrollResponse format. When the
HLRC tries to handle such responses, it blows up because it tris to parse it
expecting the error format that errors in general use. This change prompts the
HLRC to parse the response using the expected BulkByScrollResponse format.
