Improve separation of scripting between EQL and SQL by delegating common
methods to QL. The context detection is determined based on the package
to avoid having repetitive class hierarchies.
The Painless whitelists have been improved so that the declaring class
is used instead of the inherited one.

EQL: Add Substring function with Python semantics (#53688)
Does not reuse substring from SQL due to the difference in semantics and
the accepted arguments.
Currently it is missing full integration tests as, due to the usage of
scripting, requires an actual integration test against a proper cluster
(and likely its own QA project).

Today we log `failed to execute pipeline for a bulk request` at `ERROR` level
if an attempt to run an ingest pipeline fails. A failure here is commonly due
to an `EsRejectedExecutionException`. We also feed such failures back to the
client and record the rejection in the threadpool statistics.
In line with #51459 there is no need to log failures within actions so noisily
and with such urgency. It is better to leave it up to the client to react
accordingly. Typically an `EsRejectedExecutionException` should result in the
client backing off and retrying, so a failure here is not normally fatal enough
to justify an `ERROR` log at all.
This commit reduces the log level for this message to `DEBUG`.
As classification now works for multiple classes, randomly
picking training/test data frame rows is not good enough.
This commit introduces a stratified cross validation splitter
that maintains the proportion of the each class in the dataset
in the sample that is used for training the model.
Backport of #54087
Fixes an issue where the elasticsearch-node command-line tools would not work correctly
because PersistentTasksCustomMetaData contains named XContent from plugins. This PR
makes it so that the parsing for all custom metadata is skipped, even if the core system would
know how to handle it.
Closes#53549
This removes some more ceremony when declaring agg parsers. You no
longer need a static `parse` method, instead you can just make the
`PARSER` public in most cases.
There are still a few aggs with the `parse` method, but those `parse`
methods are a little more complex to untangle.
Currently the remote info api has added a number of possible fields
(proxy, num_socket_connections, etc) that are available in proxy mode.
These fields are not aligned with what the settings are named. This
commit modifies this API to align with the settings.
Wildcard queries on keyword fields get normalized, however this normalization
step should exclude the two special characters * and ? in order to keep the
wildcard query itself intact.
Closes#46300
Submit async search forces pre_filter_shard_size for the underlying search that it creates.
With this commit we also prevent users from overriding such default as part of request validation.
This commit adds an explicit cancellation of the search task if
the initial async search submit task is cancelled (connection closed by the user).
This was previously done through the cancellation of the parent task but we don't
handle grand-children cancellation yet so we have to manually cancel the search task
in order to ensure that shard actions are cancelled too.
This change can be considered as a workaround until #50990 is fixed.
* add flush always output option that will flush the output printer
after each debug message when enabled (disabled by default)
* at debug output initializationtime, log debug output
information about OS, JVM and default JVM timezone

DocsClientYamlTestSuiteIT sometimes fails for CCR
related tests because tests are started before the license
is fully applied and active within the cluster. The first
tests to be executed then fails with the error noticed
in #53430. This can be easily reproduced locally by
only running CCR docs tests.
This commit adds some @Before logic in
DocsClientYamlTestSuiteIT so that it waits for the
license to be active before running CCR tests.
Closes#53430
It is possible for ML jobs to open lazily if the "allow_lazy_open"
option in the job config is set to true. Such jobs wait in the
"opening" state until a node has sufficient capacity to run them.
This commit fixes the bug that prevented datafeeds for jobs lazily
waiting assignment from being started. The state of such datafeeds
is "starting", and they can be stopped by the stop datafeed API
while in this state with or without force.
Backport of #53918
The snapshot stats response list of snapshot statuses is not ordered according to the
given list of snapshot names so randomly we could mix up snapshot1 and snapshot2
when asserting on the stats.
Fixed by getting each snapshot's stats individually.
Closes#54034
Role names are now compiled from role templates before role mapping is saved.
This serves as validation for role templates to prevent malformed and invalid scripts
to be persisted, which could later break authentication.
Resolves: #48773
This commit instruments data frame analytics
with stats for the data that are being analyzed.
In particular, we count training docs, test docs,
and skipped docs.
In order to account docs with missing values as skipped
docs for analyses that do not support missing values,
this commit changes the extractor so that it only ignores
docs with missing values when it collects the data summary,
which is used to estimate memory usage.
Backport of #53998
add 2 additional stats: processing time and processing total which capture the
time spent for processing results and how often it ran. The 2 new stats
correspond to the existing indexing and search stats. Together with indexing
and search this now allows the user to see the full picture, all 3 stages.
This is the first in a series of commits that will introduce the
autoscaling deciders framework. This commit introduces the basic
framework for representing autoscaling decisions.
This commit switches to using an onlyIf to determine if a build Docker
image task execution should occur. This is preferred since it means that
the determination is performed at task execution time, rather than
during configuration.
This commit changes the pre_filter_shard_size default from 128 to unspecified.
This allows to apply heuristics based on the request and the target indices when deciding
whether the can match phase should run or not. When unspecified, this pr runs the can match phase
automatically if one of these conditions is met:
* The request targets more than 128 shards.
* The request contains read-only indices.
* The primary sort of the query targets an indexed field.
Users can opt-out from this behavior by setting the `pre_filter_shard_size` to a static value.
Closes#39835
I created this bug today in #53793. When a `DelayableWriteable` that
references an existing object serializes itself it wasn't taking the
version of the node on the other side of the wire into account. This
fixes that.
Adds multi-class feature importance calculation.
Feature importance objects are now mapped as follows
(logistic) Regression:
```
{
"feature_name": "feature_0",
"importance": -1.3
}
```
Multi-class [class names are `foo`, `bar`, `baz`]
```
{
“feature_name”: “feature_0”,
“importance”: 2.0, // sum(abs()) of class importances
“foo”: 1.0,
“bar”: 0.5,
“baz”: -0.5
},
```
For users to get the full benefit of aggregating and searching for feature importance, they should update their index mapping as follows (before turning this option on in their pipelines)
```
"ml.inference.feature_importance": {
"type": "nested",
"dynamic": true,
"properties": {
"feature_name": {
"type": "keyword"
},
"importance": {
"type": "double"
}
}
}
```
The mapping field name is as follows
`ml.<inference.target_field>.<inference.tag>.feature_importance`
if `inference.tag` is not provided in the processor definition, it is not part of the field path.
`inference.target_field` is defaulted to `ml.inference`.
//cc @lcawl ^ Where should we document this?
If this makes it in for 7.7, there shouldn't be any feature_importance at inference BWC worries as 7.7 is the first version to have it.
It seemed confusing for users that our top-level mapping page still had a
prominent section named 'Mapping Type'. This PR reworks the docs to remove this
reference and adds a note about types removal (similar to the note we added to
other APIs like put mapping).
Today when cluster.remote.connect is set to false, and some aspect of
the codebase tries to get a remote client, today we return a no such
remote cluster exception. This can be quite perplexing to users,
especially if the remote cluster is actually defined in their cluster
state, it is only that the local node is not a remote cluter
client. This commit addresses this by providing a dedicated error
message when a remote cluster is not available because the local node is
not a remote cluster client.
This commit removes the configuration time vs execution time distinction
with regards to certain BuildParms properties. Because of the cost of
determining Java versions for configuration JDK locations we deferred
this until execution time. This had two main downsides. First, we had
to implement all this build logic in tasks, which required a bunch of
additional plumbing and complexity. Second, because some information
wasn't known during configuration time, we had to nest any build logic
that depended on this in awkward callbacks.
We now defer to the JavaInstallationRegistry recently added in Gradle.
This utility uses a much more efficient method for probing Java
installations vs our jrunscript implementation. This, combined with some
optimizations to avoid probing the current JVM as well as deferring
some evaluation via Providers when probing installations for BWC builds
we can maintain effectively the same configuration time performance
while removing a bunch of complexity and runtime cost (snapshotting
inputs for the GenerateGlobalBuildInfoTask was very expensive). The end
result should be a much more responsive build execution in almost all
scenarios.

This moves the pipeline aggregation validation from the data node to the
coordinating node so that we, eventually, can stop sending pipeline
aggregations to the data nodes entirely. In fact, it moves it into the
"request validation" stage so multiple errors can be accumulated and
sent back to the requester for the entire request. We can't always take
advantage of that, but it'll be nice for folks not to have to play
whack-a-mole with validation.
This is implemented by replacing `PipelineAggretionBuilder#validate`
with:
```
protected abstract void validate(ValidationContext context);
```
The `ValidationContext` handles the accumulation of validation failures,
provides access to the aggregation's siblings, and implements a few
validation utility methods.
If a setting is touched during bootstrap before logging is configured,
and that setting uses a byte size value, the deprecation logger for
ByteSizeValue will be initialized. However, this means a logger will be
configured before log4j is initialized, which we reject at startup. This
commit puts this deprecation logger in a holder pattern so that it is
not initialized until first use, which will happen after logging is
configured.
