When an opened anomaly detection job is updated with a detection
rule that references a filter, apart from updating the c++ process
with the rule, we also need to update it with the referenced filter.
This commit fixes a bug which led to the job not applying such updates
on-the-fly.
Fixes#62948
Backport of #63057
Remove Count class and related artifacts since that functionality is not
(yet) available.
Update parser name for better error reporting.
Fix#62131
(cherry picked from commit 060f500346788c4c5d0b3b9c045facec5d677d3d)
Test testSortDifferentFormatsShouldFail was occasionally failing for
2 reasons:
1) Documents on "idx2" were not available for search before a
search request started
2) Running a test multiple times was causing
occasional ResourceAlreadyExistsException for idx2,
as idx2 was not deleted for a test.
This patch makes the following fixes:
1) Sets up immediate refresh policy for docs in the index"idx2"
2) Creates an index idx2 only once per cluster
Closes: #62997
This is a very minor optimization but trivial to implement, so might as well.

This measurement is in nanoseconds, consequently, the overall performance of inference is dominated by other factors (i.e. map#put). But, this optimization adds up overtime and is simple.
This commit adds bwc testing for data frame analytics.
The bwc tests only go back to the 7.9.0.
Meaning, initially only rolling upgrades from 7.9.x -> 7.10.0 are tested.
Since the feature was experimental in < 7.9.0, this is acceptable.
Data frame analytics results format changed in version `7.10.0`.
If existing jobs that were not completed are restarted, it is
possible the destination index had already been created. That index's
mappings are not suitable for the new results format.
This commit checks the version of the destination index and deletes
it when the version is outdated. The job will then continue by
recreating the destination index and reindexing.

Today InternalClusterInfoService ignores hidden indices when
retrieving shard stats of the cluster. This can lead to suboptimal
shard allocation decisions as the size of shards are taken into
account when allocating new shards or rebalancing existing shards.
This converts RankFeatureFieldMapper, RankFeaturesFieldMapper,
SearchAsYouTypeFieldMapper and TokenCountFieldMapper to
parametrized forms. It also adds a TextParams utility class to core
containing functions that help declare text parameters - mainly shared
between SearchAsYouTypeFieldMapper and KeywordFieldMapper at
the moment, but it will come in handy when we convert TextFieldMapper
and friends.

This PR adds timeouts to the named pipe connections of the
autodetect, normalize and data_frame_analyzer processes.
This argument requires the changes of elastic/ml-cpp#1514 in
order to work, so that PR will be merged before this one.
(The controller process already had a different mechanism,
tied to the ES JVM lifetime.)
Backport of #62993
Fix query creation inside sequences with any queries due to lacking a
clause to combine, which lead to an invalid request being created.
Fix#62967
(cherry picked from commit ff59d8823919a6e70928816e5c3687308ebde33f)
Classification feature importance supports various types in the class name:
- string
- boolean
- numerical
The xcontent parsing on the server side and the HLRC side should support and test these types.
* Use compilation as validation for painless role template (#62845)
Role template validation now performs only compilation if the script is painless.
It no longer attempts to execute the script with empty input which is problematic.
The compliation process will catch things like invalid syntax, undefined variables,
which still provide certain level of protection against ill-defined role templates.
Behaviour for Mustache script is unchanged.
* Checkstyle
* [ML] fixing testTwoJobsWithSameRandomizeSeedUseSameTrainingSet tests (#62976)
This fixes the two test failures.
The shard failure seems to be due to the .ml-stats index being in the middle of being created.
50_script_values/Script query fails sometimes
as resulting hits will be ordered differently from expected.
This patch ensures consisten ordering of hits.
Closes#62975
This refactors the loading of monitoring templates slightly so that they aren't loaded over and
over again (from disk) on CS updates. This isn't an important optimization in production for obvious
reasons since it only affects the install stage, but this turned out to cause some slow CS applies
in tests.

If the transform grouping is a script then exclude the field from the source index
mappings fields caps request. A null object caused an NPE in the serialisation of
FieldCapabilitiesIndexRequest.
As we have decided top level importance for classification is not useful,
it has been removed from the results from the training job. This commit
also removes them from inference.
Backport of #62486
Currently, `finishHim` can either execute on the specified executor
(in the less likely case that the local node request is the last to arrive)
or on a transport thread.
In case of e.g. `org.elasticsearch.action.admin.cluster.stats.TransportClusterStatsAction`
this leads to an expensive execution that deserializes all mapping metadata in the cluster
running on the transport thread and destabilizing the cluster. In case of this transport
action it was specifically moved to the `MANAGEMENT` thread to avoid the high cost of processing
the stats requests on the nodes during fan-out but that did not cover the final execution
on the node that received the initial request. This PR adds to ability to optionally specify the executor for the final step of the
nodes request execution and uses that to work around the issue for the slow `TransportClusterStatsAction`.
Note: the specific problem that motivated this PR is essentially the same as https://github.com/elastic/elasticsearch/pull/57937 where we moved the execution off the transport and on the management thread as a fix as well.
We support `"""` in `console` snippets to emulate kibana's CONSOLE.
CONSOLE also spits out `"""` when a json field contains a new line or a
double quote. This adds support for those sorts of responses to the
handling of `console-response` snippets.
Revises the current 'How to avoid oversharding' docs to incorporate
information from our [shard sizing blog post][0].
Changes:
* Streamlines introduction
* Adds "Things to remember" section to describe how shards work
* Adds "Guidelines" section based on blog tips
* Creates a "Fix an oversharded cluster" section

Passing FieldMappers to point parsing functions makes trying to build source-only
fields from MappedFieldTypes more complicated. This small refactoring changes
things so that the relevant parsing and factory functions from
AbstractGeometryFieldMapper are instead passed as lambdas to the PointParser
constructor.
make node resolving more robust by ignoring null values. This is a bug in
the usage of this class, however you don't want NPE's in prod. The root cause
might be a corner case. Because silencing the root cause is bad, the assert
causes a fail if assertions are enabled

We have to make sure the applier and not the accept state versions allign here.
Otherwise we can get into the situation where the data node is so slow to process
one version that the next one arrives, gets rejected and the request return with
ack `false` and we fail the assertion that the put mapping request didn't complete.
Closes#62446
JAVA_HOME is set as necessary in packaging tests, depending on whether
it is needed for no-jdk distributions or testing override behavior. We
currently rely on gradle finding java through PATH. However, JAVA_HOME
can sometimes be set by the system itself, which then leaks through to
the packaging test. This commit reworks our handling of JAVA_HOME to
pass it through for gradle, and then explicitly clear it whenever
running shell commands in packaging tests.
This test was disabled with an awaits fix, but the underlying issue has
been worked around, so the test can be re-enabled.
