Today we can only have non-affix settings updated and consumed _together_.
Yet, there are use-cases where two affix settings depend on each other which
makes using the hard without consuming updates together. Unfortunately, there is
not straight forward way to have N settings updated together in a type-safe way
having 2 still serves a large portion of use-cases.
This change allows an engine to recover from its local translog up to
the given seqno. The extended API can be used in these use cases:
When a replica starts following a new primary, it resets its index to
the safe commit, then replays its local translog up to the current
global checkpoint (see #32867).
When a replica starts a peer-recovery, it can initialize the
start_sequence_number to the persisted global checkpoint instead of the
local checkpoint of the safe commit. A replica will then replay its
local translog up to that global checkpoint before accepting remote
translog from the primary. This change will increase the chance of
operation-based recovery. I will make this in a follow-up.

Today, CapturingTransport#createCapturingTransportService creates a transport
service with a connection manager with reasonable default behaviours, but
overriding this behaviour in a consumer is a litle tricky. Additionally, the
default behaviour for opening a connection duplicates the content of the
CapturingTransport#openConnection() method.
This change removes this duplication by delegating to openConnection() and
introduces overridable nodeConnected() and onSendRequest() methods so that
consumers can alter this behaviour more easily.
Relates #32246 in which we test the mechanisms for opening connections to
unknown (and possibly unreachable) nodes.
Today `_msearch` doesn't allow modifying the `max_concurrent_shard_requests`
per sub search request. This change adds support for setting this parameter on
all sub-search requests in an `_msearch`.

Changes to split tests for keytab file test cases instead of
randomized testing for testing branches in the code in the
same test.
On windows platform, for keytab file permission test, we
required additional security permissions for the test
framework. As this was the only test that required those
permissions, skipping that test on windows platform.
The same scenario gets tested in *nix environments.

The main installation instructions page for the Windows MSI installer includes a header at the top to indicate that the installer is in beta, but the Installing Elasticsearch page does not. This commit adds the beta label to the MSI entry within the installation options.
This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.
As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:
```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```
You can instead use the much more normal:
```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `x-pack/qa/audit-tests`,
`x-pack/qa/ml-disabled`, and `x-pack/qa/multi-node` projects to use the
new versions.
This commit duplicates the `MlRestTestStateCleaner` to make sure
all ML data is removed after each test. After implementing
the job and datafeed APIs in the HLRC, we shall replace this
implementation with one using the HLRC itself.
Closes#32993
Today we are by-hand maintaining a list of CCR QA sub-projects that the
check task depends on. This commit simplifies this by finding these
sub-projects automatically and adding their check task as dependencies
of the CCR check task.
This commit moves the ML QA tests to be a sub-project of ML. The purpose
of this refactoring is to enable ML developers to run
:x-pack:plugin:ml:check and run the vast majority of a ML tests with a
single command (this still does not contain the ML REST tests, nor the
upgrade tests). This simplifies local development for faster iteration.
The maximum map count boostrap check can be a hindrance to users that do
not own the underlying platform on which they are executing
Elasticsearch. This is because addressing it requires tuning the kernel
and a platform provider might now allow this, especially on shared
infrastructure. However, this bootstrap check is not needed if mmapfs is
not in use. Today we do not have a way for the user to communicate that
they are not going to use mmapfs. This commit therefore adds a setting
that enables the user to disallow mmapfs. When mmapfs is disallowed, the
maximum map count bootstrap check is not enforced. Additionally, we
fallback to a different default index store and prevent the explicit use
of mmapfs for an index.
When discussing this test, it made little sense that testMonitoringService
would fail but not testMonitoringBulk given their similarity. So we argeed to
enable it again.

This change introduces a dedicated ConnectionManager for every RemoteClusterConnection
such that there is not state shared with the TransportService internal ConnectionManager.
All connections to a remote cluster are isolated from the TransportService but still uses
the TransportService and it's internal properties like the Transport, tracing and internal
listener actions on disconnects etc.
This allows a remote cluster connection to have a different lifecycle than a local cluster connection,
also local discovery code doesn't get notified if there is a disconnect on from a remote cluster and
each connection can use it's own dedicated connection profile which allows to have a reduced set of
connections per cluster without conflicting with the local cluster.
Closes#31835
* [DOCS] Add configurable password hashing docs
Adds documentation about the newly introduced configuration option
for setting the password hashing algorithm to be used for the users
cache and for storing credentials for the native and file realm.
When the application privileges feature was backported to 6.x/6.4 the
BWC version checks on the backport were updated to 6.4.0, but master
was not updated.
This commit updates all relevant version checks, and adds tests.
This commit adds troubleshooting section for Kerberos.
Most of the times the problems seen are caused due to invalid
configurations like keytab missing principals or credentials
not up to date. Time synchronization is an important part for
Kerberos infrastructure and the time skew can cause problems.
To debug further documentation explains how to enable JAAS
Kerberos login module debugging and Kerberos/SPNEGO debugging
by setting JVM system properties.
This commit implements licensing for CCR. CCR will require a platinum
license, and administrative endpoints will be disabled when a license is
non-compliant.
* INGEST: Move all Pipeline State into IngestService
* Moves all pipeline state into the ingest service
* Retains the existing pipeline store and pipeline execution service as inner classes to make the review easier, they should be flattened out in the next step
* All tests for these classes were copied (and adapted) to the ingest service tests
* This is a refactoring step to enable a clean implementation of a pipeline processor (See #32473)
There are two problems with the scheduler engine today. Both relate to
listeners that throw.
The first problem is that any triggered listener that throws a plain old
exception will cause no additional listeners to be triggered for the
event, and will also cause the scheduler to never be invoked again. This
leads to lost events and is bad.
The second problem is that any triggered listener that throws an error
of the fatal kind will not lead to that error because caught by the
uncaught exception handler. This is because the triggered listener is
executed as a future task under a scheduled thread pool executor. A
throwable there goes caught by the JDK framework and set as the outcome
on the future task. Since we never inspect these tasks for their
outcomes, nor is there a good place to do this, we have to handle these
errors ourselves. To do this, we catch them and dispatch them to the
uncaught exception handler via a forked thread. This is similar to our
handling in Netty.

Machine learning has baked a remote license checker for use in checking
license compatibility of a remote license. This remote license checker
has general usage for any feature that relies on a remote cluster. For
example, cross-cluster replication will pull changes from a remote
cluster and require that the local and remote clusters have platinum
licenses. This commit generalizes the remote cluster license check for
use in cross-cluster replication.
Since #28140 when the global checkpoint is advanced, we try to move the
safe commit forward, and clean up old index commits if possible. However,
we forget to trim unreferenced translog.
This change makes sure that we prune both old translog and index commits
when the safe commit advanced.

Subclasses of `EsIntegTestCase` run multiple Elasticsearch nodes in the

include the node name.

I'd like to follow this up with more drastic changes that make it
impossible to do this incorrectly but that change is much larger than
this and I'd like to get these log lines fixed up sooner rather than
later.
All Translog inner closes should happen after tragedy exception is set (#32674)
We faced with the nasty race condition. See #32526
InternalEngine.failOnTragic method has thrown AssertionError.
If you carefully look at if branches in this method, you will spot that its only possible, if either Lucene IndexWriterhas closed from inside or Translog, has closed from inside, but tragedy exception is not set.
For now, let us concentrate on the Translog class.
We found out that there are two methods in Translog - namely rollGeneration and trimOperations that are closing Translog in case of Exception without tragedy exception being set.
This commit fixes these 2 methods. To fix it, we pull tragedyException from TranslogWriter up-to Translog class, because in these 2 methods IndexWriter could be innocent, but still Translog needs to be closed. Also, tragedyException is wrapped with TragicExceptionHolder to reuse CAS/addSuppresed functionality in Translog and TranslogWriter.
Also to protect us in the future and make sure close method is never called from inside Translog special assertion examining stack trace is added. Since we're still targeting Java 8 for runtime - no StackWalker API is used in the implementation.
In the stack-trace checking method, we're considering inner caller not only Translog methods but Translog child classes methods as well. It does mean that Translog is meant for extending it, but it's needed to be able to test this method.
Closes#32526
This is related to #32517. This commit passes the DiscoveryNode to the
initiateChannel method for different Transport implementation. This
will allow additional attributes (besides just the socket address) to be
