Today closing a `ClusterNode` in an `AbstractCoordinatorTestCase` uses
`onNode()` so has no effect if the node is not in the current list of nodes.
It also discards the `Runnable` it creates without having run it, so has no
effect anyway.
This commit makes these tests much stricter about properly closing the nodes
started during `Coordinator` tests, by tracking the persisted states that are
opened, and adds an assertion to catch the trappy requirement that the closing
node still belongs to the cluster.
This commit fixes a bug when a deferred aggregator tries to early terminate the collection. In such case the CollectionTerminatedException is not caught and
the search fails on the shard. This change makes sure that we catch the exception in order to continue the deferred collection on the next leaf.
Fixes#44909
The existing equals check was broken, and would always be false.
The correct behaviour is to return "Collections.emptyList()" whenever
the the active(licensed)-realms equals the configured-realms.

* Rename indexlifecycle to ilm and snapshotlifecycle to slm (#44917)
As a followup to #44725 and #44608, which renamed the packages within
the x-pack project, this renames the packages within the core x-pack
project. It also renames 'snapshotlifecycle' within the HLRC to slm.
* Fix one more import
Replaying operations from the local translog must never fail as those
operations were processed successfully on the primary before and the
mapping is up to update already. This change removes leniency during
resetting engine from translog in IndexShard and InternalEngine.
This is a temporary fix during the Joda to Java datetime transition. This will
implicitly cast a JodaCompatibleZonedDateTime to a ZonedDateTime for
both def and static types. This is necessary to insulate users from needing
to know about JodaCompatibleZonedDateTime explicitly.
In case closing the process throws an exception we should be catching
it no matter its type. The process may have terminated because of a
fatal error in which case closing the process will throw a server
error, not an `IOException`. If this happens we fail to mark the
persistent task as failed and the task gets in limbo.
As data frame rows with missing values for analyzed fields are skipped,
we can be more efficient by including a query that only picks documents
that have values for all analyzed fields. Besides improving the number
of documents we go through, we also provide a more accurate measurement
of how many rows we need which reduces the memory requirements.
This also adds an integration test that runs outlier detection on data
with missing fields.
TaskListener accepts today Throwable in its onFailure method. Though
looking at where it is called (TransportAction), it can never be
notified of a Throwable.
This commit changes the signature of TaskListener#onFailure so that it
accepts an `Exception` rather than a `Throwable` as second argument.
We currently block the transport thread on startup, which has caused test failures. I think this is
some kind of deadlock situation. I don't think we should even block a transport thread, and
there's also no need to do so. We can just reject requests as long we're not fully set up. Note
that the HTTP layer is only started much later (after we've completed full start up of the
transport layer), so that one should be completely unaffected by this.
Closes#41745
Fixes an issue where a call to openConnection was not properly guarded, allowing an exception
to bubble up to the uncaught exception handler, causing test failures.
Closes#44912
In order to make it easier to interpret the output of the ILM Explain
API, this commit adds two request parameters to that API:
- `only_managed`, which causes the response to only contain indices
which have `index.lifecycle.name` set
- `only_errors`, which causes the response to contain only indices in an
ILM error state
"Error state" is defined as either being in the `ERROR` step or having
`index.lifecycle.name` set to a policy that does not exist.
SimpleClusterStateIT testIndicesOptions failed in #44817 because it tries to close
an index at the beginning of the test. With random index settings, it is possible that
the index has a high number of shards (10) and replicas (1), which means that on
CI this index can take time to be fully allocated.
The close index request can fail in the case where replicas are still recovering operations.
Thiscommit adds a simple ensureGreen() at the beginning of the test to be sure that all
replicas are started before trying to close the index.

This PR addresses the feedback in https://github.com/elastic/ml-team/issues/175#issuecomment-512215731.
* Adds an example to `analyzed_fields`
* Includes `source` and `dest` objects inline in the resource page
* Lists `model_memory_limit` in the PUT API page
* Amends the `analysis` section in the resource page
* Removes Properties headings in subsections
The test ShrinkIndexIT.testShrinkThenSplitWithFailedNode sometimes fails
because the resize operation is not acknowledged (see #44736). This resize
operation creates a new index "splitagain" and it results in a cluster state
update (TransportResizeAction uses MetaDataCreateIndexService.createIndex()
to create the resized index). This cluster state update is expected to be
acknowledged by all nodes (see IndexCreationTask.onAllNodesAcked()) but
this is not always true: the data node that was just stopped in the test before
executing the resize operation might still be considered as a "faulty" node
(and not yet removed from the cluster nodes) by the FollowersChecker. The
cluster state is then acked on all nodes but one, and it results in a non
acknowledged resize operation.
This commit adds an ensureStableCluster() check after stopping the node in
the test. The goal is to ensure that the data node has been correctly removed
from the cluster and that all nodes are fully connected to each before moving
forward with the resize operation.
Closes#44736
Today the processors setting is permitted to be set to more than the
number of processors available to the JVM. The processors setting
directly sizes the number of threads in the various thread pools, with
most of these sizes being a linear function in the number of
processors. It doesn't make any sense to set processors very high as the
overhead from context switching amongst all the threads will overwhelm,
and changing the setting does not control how many physical CPU
resources there are on which to schedule the additional threads. We have
to draw a line somewhere and this commit deprecates setting processors
to more than the number of available processors. This is the right place
to draw the line given the linear growth as a function of processors in
most of the thread pools, and that some are capped at the number of
available processors already.
Since 7.3, it's possible to explicitly configure the SAML realm to
be used in Kibana's configuration. This in turn, eliminates the need
of properly setting `xpack.security.public.*` settings in Kibana
and largely simplifies relevant documentation.
This also changes `xpack.security.authProviders` to
`xpack.security.authc.providers` as the former was deprecated in
favor of the latter in 7.3 in Kibana
With this change, we will return primary_term and seq_no of the current
document if an update is detected as a noop. We already return the
version; hence we should also return seq_no and primary_term.
Relates #42497
Adds an API to clone an index. This is similar to the index split and shrink APIs, just with the
difference that the number of primary shards is kept the same. In case where the filesystem
provides hard-linking capabilities, this is a very cheap operation.
Indexing cloning can be done by running `POST my_source_index/_clone/my_target_index` and it
supports the same options as the split and shrink APIs.
Closes#44128
This change allows the Kotlin compiler to type check methods annotated with the
org.elasticsearch.common.Nullable annotation in Elasticsearch Java
APIs as described in: https://kotlinlang.org/docs/reference/java-interop.html#jsr-305-support.
