The remote_monitoring_user user needs to access the enrich stats API.
But the request is denied because the API is categorized under admin.
The correct privilege should be monitor.
Adds parsing of `status` and `memory_reestimate_bytes`
to data frame analytics `memory_usage`. When the training surpasses
the model memory limit, the status will be set to `hard_limit` and
`memory_reestimate_bytes` can be used to update the job's
limit in order to restart the job.

Java 9 removed pathname canonicalization, which means that we need to
add permissions for the path and also the real path when adding file
permissions. Since master requires a minimum runtime of JDK 11, we no
longer need conditional logic here to apply this pathname
canonicalization with our bares hands. This commit removes that
conditional pathname canonicalization.

`descendsFromBucketAggregator` was important before we removed
`asMultiBucketAggregator` but now that it is gone
`collectsFromSingleBucket` is good enough.

Today SparseFileTracker allows to wait for a range to become available
before executing a given listener. In the case of searchable snapshot,
we'd like to be able to wait for a large range to be filled (ie, downloaded
and written to disk) while being able to execute the listener as soon as
a smaller range is available.
This pull request is an extract from #58164 which introduces a
ProgressListenableActionFuture that is used internally by
SparseFileTracker. The progressive listenable future allows to register
listeners attached to SparseFileTracker.Gap so that they are executed
once the Gap is completed (with success or failure) or as soon as the
Gap progress reaches a given progress value. This progress value is
defined when the tracker.waitForRange() method is called; this method
has been modified to accept a range and another listener's range to
operate on.

Replaces `composable index template` and `composable template` with
`index template` throughout data stream-related docs.
`Composable index template` is only used to contrast with legacy index
templates.
Removes references to partial results from the async EQL search docs.
If an EQL search does not complete during the `wait_for_completion_timeout`
timeout period, it returns no results.
Minor bugs/inconsistencies:
If a shard hasn't changed at all we were reporting `0` for total size and total file count
while it was ongoing.
If a data node restarts/drops out during snapshot creation the fallback logic did not load the correct statistic from the repository but just created a status with `0` counts from the snapshot state in the CS. Added a fallback to reading from the repository in this case.
Changes the titles for tokenizer pages to sentence case.
Also moves the 'Path hierarchy tokenizer examples' page within the
'Path hierarchy tokenizer' page and adds a related redirect.
This commit converts the bats tests for the plugin cli into the java
packaging test framework. The new tests only use the example plugin to
test the plugin cli. The tests for each individual plugin's contents
after being installed are handled by a new unit test for the plugin
installer added in #58287.
We're tracking this aggregation's experimental-progress in #58573. We'd
like a little time to be able to make backwards incompatible changes to
the aggregation because we're not 100% sure about the request and
response format yet.
If a project is pulling in an external org.elasticsearch dependency, the dependency
report generation would require a license file for the dependency to be present.
This would break precommit because a license was present that it did not feel was
warranted. This un-reverts the update to the dependenciesInfo task, as well as the
JNA license addition.
In SLM retention, when a minimum number of snapshots is required for retention, we prefer to remove
the oldest snapshots first. To perform this, we limit one of the streams, in a rare case this can
cause:
```

When certain criteria are met. This commit fixes the negative limiting with `Math.max(0, ...)` and
adds a unit test for the behavior.
Resolves#58515
Fixes two bugs introduced by #57627:
1. We were not properly letting go of memory from the request breaker
when the aggregation finished.
2. We no longer supported totally arbitrary stuff produced by the init
script because we *assumed* that it'd be ok to run the script once
and clone its results. Sadly, cloning can't clone *anything* that the
init script can make, like `String` arrays. This runs the init script
once for every new bucket so we don't need to clone.
If we failed over while the data nodes were doing their work
we would never resolve the listener and leak it.
This change fails all listeners if master fails over.
Rather than let ExtensiblePlugins know extending plugins' classloaders,
we now pass along an explicit ExtensionLoader that loads the extensions
asked for. Extensions constructed that way can optionally receive their
own Plugin instance in the constructor.
Today we have individual settings for configuring node roles such as
node.data and node.master. Additionally, roles are pluggable and we have
used this to introduce roles such as node.ml and node.voting_only. As
the number of roles is growing, managing these becomes harder for the
user. For example, to create a master-only node, today a user has to
configure:
- node.data: false
- node.ingest: false
- node.remote_cluster_client: false
- node.ml: false
at a minimum if they are relying on defaults, but also add:
- node.master: true
- node.transform: false
- node.voting_only: false
If they want to be explicit. This is also challenging in cases where a
user wants to have configure a coordinating-only node which requires
disabling all roles, a list which we are adding to, requiring the user
to keep checking whether a node has acquired any of these roles.
This commit addresses this by adding a list setting node.roles for which
a user has explicit control over the list of roles that a node has. If
the setting is configured, the node has exactly the roles in the list,
and not any additional roles. This means to configure a master-only
node, the setting is merely 'node.roles: [master]', and to configure a
coordinating-only node, the setting is merely: 'node.roles: []'.
With this change we deprecate the existing 'node.*' settings such as
'node.data'.
* [ML] make waiting for renormalization optional for internally flushing job (#58537)
When flushing, datafeeds only need the guaruntee that the latest bucket has been handled.
But, in addition to this, the typical call to flush waits for renormalization to complete. For large jobs, this can take a fair bit of time (even longer than a bucket length). This causes unnecessary delays in handling data.
This commit adds a new internal only flag that allows datafeeds (and forecasting) to skip waiting on renormalization.
closes#58395
This commit restores the filtering of empty fields during the
xcontent serialization of SearchHit. The filtering was removed
unintentionally in #41656.
Implements a new histogram aggregation called `variable_width_histogram` which
dynamically determines bucket intervals based on document groupings. These
groups are determined by running a one-pass clustering algorithm on each shard
and then reducing each shard's clusters using an agglomerative
clustering algorithm.
This PR addresses #9572.
The shard-level clustering is done in one pass to minimize memory overhead. The
algorithm was lightly inspired by
[this paper](https://ieeexplore.ieee.org/abstract/document/1198387). It fetches
a small number of documents to sample the data and determine initial clusters.
Subsequent documents are then placed into one of these clusters, or a new one
if they are an outlier. This algorithm is described in more details in the
aggregation's docs.
At reduce time, a
[hierarchical agglomerative clustering](https://en.wikipedia.org/wiki/Hierarchical_clustering)
algorithm inspired by [this paper](https://arxiv.org/abs/1802.00304)
continually merges the closest buckets from all shards (based on their
centroids) until the target number of buckets is reached.
The final values produced by this aggregation are approximate. Each bucket's
min value is used as its key in the histogram. Furthermore, buckets are merged
based on their centroids and not their bounds. So it is possible that adjacent
buckets will overlap after reduction. Because each bucket's key is its min,
this overlap is not shown in the final histogram. However, when such overlap
occurs, we set the key of the bucket with the larger centroid to the midpoint
between its minimum and the smaller bucket’s maximum:
`min[large] = (min[large] + max[small]) / 2`. This heuristic is expected to
increases the accuracy of the clustering.
Nodes are unable to share centroids during the shard-level clustering phase. In
the future, resolving https://github.com/elastic/elasticsearch/issues/50863
would let us solve this issue.
It doesn’t make sense for this aggregation to support the `min_doc_count`
parameter, since clusters are determined dynamically. The `order` parameter is
not supported here to keep this large PR from becoming too complex.

The main changes are:
1. Catch the `NamedObjectNotFoundException` when parsing aggregation
type, and then throw a `ParsingException` with clear error message with hint.
2. Add a unit test method: AggregatorFactoriesTests#testInvalidType().
Closes#58146.

It is possible for the source document to have an empty string value
for a field that is mapped as numeric. We should treat those as missing
values and avoid throwing an assertion error.
Backport of #58541
This changes the default value for the results field of inference
applied on models that are trained via a data frame analytics job.
Previously, the results field default was `predicted_value`. This
commit makes it the same as in the training job itself. The new
default field is `<dependent_variable>_prediction`. Apart from
making inference consistent with the training job the model came
from, it is helpful to preserve the dependent variable name
by default as it provides some context to the user that may
avoid confusion as to which model results came from.
Backport of #58538
If a persistent task cannot be assigned on the first attempt
then the master node will schedule periodic rechecks to see
if the assignment requirements have been met.
These periodic rechecks should be cancelled if the node ceases
to be master. Previously they weren't, leading to exceptions
being logged repeatedly. This PR cancels the rechecks on
learning that the node is no longer the master.
Fixes#58531
* Enable TTY password OS tests, plus refactoring (#57759)
Two keystore tests were unintentionally ignored when the
password-protected keystore work was merged. I've reënabled those tests
here.
I've also refactored the test methods a little bit to reduce the API
surface: instead of having a "startElasticsearchTtyPassword" method and
a "startElasticsearchStandardInputPassword" method, I've made a single
"startElasticsearch" method with a "useTty" boolean argument.
* Separate daemonization and non-daemonization case for tty
Centos 6 uses a version of expect that kills the elasticsearch process
when it tries to daemonize. I will fix this in future work but for now
I'm replacing it with a todo.
Follow-up to 35aecf4c9aa. Somehow I missed the fact that there's an ILM
API named `retry`, which is a keyword in Ruby. I've removed it from the
keywords list.
If an API name (or components of a name) overlaps with a reserved word in
the programming language for an ES client, then it's possible that the code
that is generated from the API will not compile. This PR adds validation to
check for such overlaps.
With #58096, data streams now track the timestamp field mapping outside
of the template associated with the stream. This means you can no longer
update the timestamp field mapping using template changes.
This updates the associated data stream docs.
When creating a target index from a source index, we don't allow for target
mappings to be specified. This PR simplifies the check that the target mappings
are empty.
This refactor will help when implementing composable template merging, since we
no longer need to resolve + check the target mappings when creating an index
from a template.
* Add acm mapping to APM for beats
* Add root mapping for APM
* Add sourcemap mapping to APM
* Fix missing properties
* Fix a second missing properties
* Add request property to acm
* Remove root and sourcemap per review

Netty4HttpServerTransportTests has started to fail intermittently. It
seems like unexpected successful responses are being received when the
test is simulating errors. This commit adds logging to the test to
provide additional information when there is an unexpected success. It
also adds the logging to the nio http test.
The plugin installer currently checks the fake plugins installed contain
a single jar file. This commit adds another test for a plugin which
contains multiple jar files, ensuring all jars exist in the installed
plugin.
Add the ability to get a custom value while specifying a default and use it throughout the
codebase to get rid of the `null` edge case and shorten the code a little.
