This is a followup to #44350. The indexer stats used to
be persisted standalone, but now are only persisted as
part of a state-and-stats document. During the review
of #44350 it was decided that we'll stick with this
design, so there will never be a need for an indexer
stats object to store its transform ID as it is stored
on the enclosing document. This PR removes the indexer
stats document ID.

The problem is that RemoteClusterConnection closes the connection manager asynchronously, which races with the threadpool being shutdown at the end of the test.
Closes#44339Closes#44610
Deleting a follower index does not delete its ShardFollowTasks, potentially
leaving many persistent tasks in the cluster that cannot be allocated on
nodes and unnecessary fill the logs. This commit adds a cluster state listener
(ShardFollowTaskCleaner) that completes (with a failure) any persistent task
that refers to a non existent follower index.
I think that this bug has been introduced by #34404: before this change the
task would have been completed as failed and removed from the cluster state.

* Switch from using docvalue_fields to extracting values from _source
where applicable. Doing this means parsing the _source and handling the
numbers parsing just like Elasticsearch is doing it when it's indexing
a document.
* This also introduces a minor limitation: aliases type of fields that
are NOT part of a tree of sub-fields will not be able to be retrieved
anymore. field_caps API doesn't shed any light into a field being an
alias or not and at _source parsing time there is no way to know if a
root field is an alias or not. Fields of the type "a.b.c.alias" can be
extracted from docvalue_fields, only if the field they point to can be
extracted from docvalue_fields. Also, not all fields in a hierarchy of
fields can be evaluated to being an alias.

We already have a note that the order of actions is up to ILM for each
phase, this commit puts the actions in the same order as they will be
executed.
Resolves#41729
This test can fail (super-rarely) if it generates a list of length 11
containing a duplicate, because the `.distinct()` reduces the list length to 10
and then it is not abbreviated any more. This change generalises the test to
cover lists of any random length.
* The tests were creating the corruption and asserting its existence not on the repository base path but on a clean path.
As a result the consistency assertion on the repository wouldn't see the corruption ever an pass even if the cleanup was broken for repositories that have a non-root base path
Use InspectionHelper classes to decide if the aggregations should return null (in case there is no value) or the value itself.

* In both fake connection validators we were potentially executing the listener twice. This lead to the situation that the locking via `connectionLock` that ensures that each listener is only executed once ever
would fail and the lister would run twice (in which case the listeners for that node are already `null` and we get an NPE)
* The fact that two different tests fail is due to the fact that we weren't safely shutting down the threadpool which meant the the task that trips the assertion (on the generic pool) would leak into the next test and fail it
* Closes#44758
These fields can be final, since they are set at construction, and
changing them after that could lead to some confusing test cases. This
commit allows the compiler to enforce that we never modify these values
during tests.
* Only emit deprecation warning if there was actual change of a datafeed's job_id.
* Add @Deprecated annotation to DatafeedUpdate.Builder#setJobId method
This commit more closely aligns the assertion that we are running in a
package distribution with disabling the systemd integration if somehow
we running on not a package distribution. This is, previously we had an
assertion that we are in a package distribution (RPM or Debian package)
but would disable the systemd integration if we are not on
Linux. Instead, we should disable the systemd integration if we are not
running in a package distribution. Because of our assertion, we expect
this to never hold, but we need a fallback for when this assertion is
violated and assertions are not enabled.
Well, we have a test here that intentionally causes an OutOfMemoryError,
to ensure that Painless handles it (I still strongly disagree with doing
this). This causes two things to happen: an OutOfMemoryError to be
dumped to the console, and the heap to be dumped to disk. This makes it
look like we had an OutOfMemoryError while running tests, and the tests
did not fail properly. This commit changes the tests configuration so
that we suppress the heap dump, which also causes the OutOfMemoryError
to no longer be dumped to the console.
We have some old permissions lying around, granted to untrusted code
from the days of yore when we supported Groovy and Javascript
scripting. This commit removes these stale permissions.
Today our systemd service defaults to a service type of simple. This
means that systemd assumes Elasticsearch is ready as soon as the
ExecStart (bin/elasticsearch) process is forked off. This means that the
service appears ready long before it actually is, so before it is ready
to receive requests. It also means that services that want to depend on
Elasticsearch being ready to start can not as there is not a reliable
mechanism to determine this. This commit changes the service type to
notify. This requires that Elasticsearch sends a notification message
via libsystemd sd_notify method. This commit does that by using JNA to
invoke this native method. Additionally, we use this integration to also
notify systemd when we are stopping.
* Fix this test randomly failing when running into async translog persistence edge case and failing to successfully close index
* Also, slightly improve debug logging on close failure

Switches to more robust way of generating random test geometries by
reusing lucene's GeoTestUtil. Removes duplicate random geometry
generators by moving them to the test framework.

The `// TEARDOWN` test snippet was added with #34716. You can use this
snippet to end and clean up a test series started with `// TESTSETUP` or
`// TEST[setup:name]`.
This change adjusts the data frame transforms stats
endpoint to return a structure that is easier to
understand.
This is a breaking change for clients of the data frame
transforms stats endpoint, but the feature is in beta so
stability is not guaranteed.
Backport of #44350
The `elasticsearch-node override-version` command fails if it cannot read the
existing node metadata file. However, it reads this file strictly and fails if
there are any unknown fields, which means it will not be useful if we add
another field in future.
This commit adds leniency to this command, allowing it to ignore any unknown
fields and proceed with the downgrade. A downgrade is already unsafe, and the
user is already copiously warned about this, so being lenient in this case does
not make things much worse.
Today when creating an index and checking cluster shard limits, we check
the number of shards before applying index templates. At this point, we
do not know the actual number of shards that will be used to create the
index. In a case when the defaults are used and a template would
override, we could be grossly underestimating the number of shards that
would be created, and thus incorrectly applying the limits. This commit
addresses this by checking the shard limits after applying index
templates.
This commit renames the ILM package from indexlifecycle to ilm. We have
all come to know index lifecycle management as ILM, the APIs and
settings use ilm, and it would be nice of the package did too. This
commit makes that change.
Some small clarifications about force-merging and global ordinals, particularly
that global ordinals are cheap on a single-segment index and how this relates
to frozen indices.
Fixes#41687
This commit renames the SLM package from snapshotlifecycle to slm. We
have all come to know index lifecycle management as ILM, the APIs and
settings use ilm, and it would be nice of the package did too. For SLM,
let's use slm for all of these including the package name from the
beginning.
