Reindex, update by query and delete by query would silently disregard
RED/unavailable shards, thus not copying, updating or deleting matching
data in those shards. Now use `allow_partial_search_results=false` to
ensure these operations fail if the search crosses an unavailable chard.
Added the option to explicitly specify `allow_partial_search_results=true`
for reindex only (seemed too strange for update/delete by query).

* [ML] ML Model Inference Ingest Processor (#49052)
* [ML][Inference] adds lazy model loader and inference (#47410)
This adds a couple of things:
- A model loader service that is accessible via transport calls. This service will load in models and cache them. They will stay loaded until a processor no longer references them
- A Model class and its first sub-class LocalModel. Used to cache model information and run inference.
- Transport action and handler for requests to infer against a local model

The logic for `cleanupInProgress()` was backwards everywhere (method itself and
all but one user). Also, we weren't checking it when removing a repository.
This lead to a bug (in the one spot that didn't use the method backwards) that prevented
the cleanup cluster state entry from ever being removed from the cluster state if master
failed over during the cleanup process.
This change corrects the backwards logic, adds a test that makes sure the cleanup
is always removed and adds a check that prevents repository removal during cleanup
to the repositories service.
Also, the failure handling logic in the cleanup action was broken. Repeated invocation would lead to the cleanup being removed from the cluster state even if it was in progress. Fixed by adding a flag that indicates whether or not any removal of the cleanup task from the cluster state must be executed. Sorry for mixing this in here, but I had to fix it in the same PR, as the first test (for master-failover) otherwise would often just delete the blocked cleanup action as a result of a transport master action retry.
The `string` type (with option `analyzed`) has been replaced by `text` after `6.0`,
also the `annonated_text` field do not support doc values and should be mentioned.
* Better Exceptions on Concurrent Snapshot Operations
It is somewhat tricky to debug test failures from concurrent operations
without having the exact knowledge of what ran concurrently so I added
it to these exceptions in all spots.
The network disruption was acting on node ids and node names
which made reconnects not work. Moved all usages to node names
to fix this. Since the map of all nodes in the test is indexed
by name this was easier to work with.
Similarly to what has been done for Azure (#48636) and GCS (#48762),
this committ removes the existing Ant fixture that emulates a S3 storage
service in favor of multiple docker-compose based fixtures.
The goals here are multiple: be able to reuse a s3-fixture outside of the
repository-s3 plugin; allow parallel execution of integration tests; removes
the existing AmazonS3Fixture that has evolved in a weird beast in
dedicated, more maintainable fixtures.
The server side logic that emulates S3 mostly comes from the latest
HttpHandler made for S3 blob store repository tests, with additional
features extracted from the (now removed) AmazonS3Fixture:
authentication checks, session token checks and improved response
errors. Chunked upload request support for S3 object has been added
too.
The server side logic of all tests now reside in a single S3HttpHandler class.
Whereas AmazonS3Fixture contained logic for basic tests, session token
tests, EC2 tests or ECS tests, the S3 fixtures are now dedicated to each
kind of test. Fixtures are inheriting from each other, making things easier
to maintain.
improve error handling for script errors, treating it as irrecoverable errors which puts the task
immediately into failed state, also improves the error extraction to properly report the script
error.

AutoFollowIT relies on assertBusy() calls to wait for a given number of
leader indices to be created but this is prone to failures on CI. Instead,
we should use latches to indicate when auto-follow patterns must be
paused and resumed.
This commit fixes a NPE problem as reported in #49150.
But this problem uncovered that we never added proper handling
of state for data frame analytics tasks.
In this commit we improve the `MlTasks.getDataFrameAnalyticsState`
method to handle null tasks and state tasks properly.

Prior to 3a3e5f6, there was no default indent configured in
`.editorconfig`. This changed to 4 spaces when we configured an explicit
indent of 2 for Gradle files. However, this change meant that YAML files
then had 4-space indents, which is valid, but the repo's YAML files
typically use 2-space indents.
Remove the default indent again, and instead explicitly set an indent size
for a variety of file types.

If CCR encounters a rejected execution exception, today we treat this as
fatal. This is not though, as the stuffed queue could drain. Requiring
an administrator to manually restart the follow tasks that faced such an
exception is a burden. This commit addresses this by making CCR
auto-retry on rejected execution exceptions.
We can't guarantee expected request failures if search request is across
many indexes, as if expected shards fail, some indexes may return 200.

* Make FsBlobContainer Listing Resilient to Concurrent Modifications

The JdbcHttpClientRequestTests and HttpClientRequestTests classes both
hold a static reference to a mock web server that internally uses the
JDKs built-in HttpServer, which resides in a sun package that the
RamUsageEstimator does not have access to. This causes builds that use
a runtime of Java 8 to fail since the StaticFieldsInvariantRule is run
when Java 8 is used.

The Apache Commons Daemon has some helpful features for Java
applications, like nice little next boxes for min heap, max heap, and
thread stack size. Our elasticsearch-service.bat script parses those
values out of the ES_JAVA_OPTS environment variable and provides them to
the Apache Commons Daemon invocation command in order to provide
sensible defaults. However, we failed to remove those values from the
ES_JAVA_OPTS environment variable, which meant they ended up in the
"Java Options" text box and would, from there, override whatever the
user put in the specific boxes for heap size or thread stack size.
This commit modifies the loop that parses ES_JAVA_OPTS to construct a
new enviroment variable containing only the values that aren't parsed
out for heap size or thread stack size, then uses that new enviroment
variable in the commons daemon invocation command.
Make queries on the “_index” field fast-fail if the target shard is an index that doesn’t match the query expression. Part of the “canMatch” phase optimisations.

ESIntegTestCase has logic to clean up static fields in a method
annotated with `@AfterClass` so that these fields do not trigger the
StaticFieldsInvariantRule. However, during the exceptional close of the
test cluster, this cleanup can be missed. The StaticFieldsInvariantRule
always runs and will attempt to inspect the size of the static fields
that were not cleaned up. If the `currentCluster` field of
ESIntegTestCase references an InternalTestCluster, this could hold a
reference to an implementation of a `Path` that comes from the
`sun.nio.fs` package, which the security manager will deny access to.
This casues additional noise to be generated since the
AccessControlException will cause the StaticFieldsInvariantRule to fail
and also be reported along with the actual exception that occurred.
This change clears the static fields of ESIntegTestCase in a finally
block inside the `@AfterClass` method to prevent this unnecessary noise.
Closes#41526
When triggered either by becoming master, a new cluster state, or a
periodic schedule, an ILM policy execution through
`maybeRunAsyncAction`, `runPolicyAfterStateChange`, or
`runPeriodicStep` throwing an exception will cause the loop the
terminate. This means that any indices that would have been processed
after the index where the exception was thrown will not be processed by
ILM.
For most execution this is not a problem because the actual running of
steps is protected by a try/catch that moves the index to the ERROR step
in the event of a problem. If an exception occurs prior to step
execution (for example, in fetching and parsing the current
policy/step) however, it causes the loop termination previously
mentioned.
This commit wraps the invocation of the methods specified above in a
try/catch block that provides better logging and does not bubble the
exception up.
* Move env vars to script, add build scan wrapper
Having the env vars being set up in the build script makes it easier to
reason about.
This PR also adds the gradle scan wrapper back as support for it was
added t o jjbb.
* Add explanatory comment
JDK 14 has removed CMS. This commit restricts the support for CMS to JDK
8 through JDK 13, and defaults to G1 GC on JDK 14. We will revisit all
defaults in the future, but this ensures that we run with a
properly-configured garbage collector on JDK 14+.
Backport of #47468 to 7.x
This PR adds a new metric aggregation called string_stats that operates on string terms of a document and returns the following:
min_length: The length of the shortest term
max_length: The length of the longest term
avg_length: The average length of all terms
distribution: The probability distribution of all characters appearing in all terms
entropy: The total Shannon entropy value calculated for all terms
This aggregation has been implemented as an analytics plugin.
The rollover action is now a retryable step (see #48256)
so ILM will keep retrying until it succeeds as opposed to stopping and
moving the execution in the ERROR step.

Ensures that methods that are called from different threads ( i.e.
from the callbacks of org.apache.http.concurrent.FutureCallback )
catch `Exception` instead of only the expected checked exceptions.
This resolves a bug where OpenIdConnectAuthenticator#mergeObjects
would throw an IllegalStateException that was never caught causing
the thread to hang and the listener to never be called. This would
in turn cause Kibana requests to authenticate with OpenID Connect
to timeout and fail without even logging anything relevant.
This also guards against unexpected Exceptions that might be thrown
by invoked library methods while performing the necessary operations
in these callbacks.
This is intended as a stop-gap solution/improvement to #38941 that
prevents repo modifications without an intermittent master failover
from causing inconsistent (outdated due to inconsistent listing of index-N blobs)
`RepositoryData` to be written.
Tracking the latest repository generation will move to the cluster state in a
separate pull request. This is intended as a low-risk change to be backported as
far as possible and motived by the recently increased chance of #38941
causing trouble via SLM (see https://github.com/elastic/elasticsearch/issues/47520).
