This commit adds functionality so that aliases that are manipulated on
leader indices are replicated by the shard follow tasks to the follower
indices. Note that we ignore write indices. This is due to the fact that
follower indices do not receive direct writes so the concept is not
useful.

This commit performs the proper restore of network disruption.
Previously disruptionScheme.stopDisrupting() was called that does not
ensure that connectivity between cluster nodes is restored. The test
was checking that the cluster has green status, but it was not checking
that connectivity between nodes is restored.
Here we switch to internalCluster().clearDisruptionScheme(true) which
performs both checks before returning.

The control flow in TransportAnalyzeAction is currently spread across two large
methods, and is quite difficult to follow. This commit tidies things up a bit, to make
it clearer when we use pre-defined analyzers and when we use custom built ones.
This commit clones the existing AnalyzeRequest/AnalyzeResponse classes
to the high-level rest client, and adjusts request converters to use these new
classes.
This is a prerequisite to removing the Streamable interface from the internal
server version of these classes.
IntervalBuilder#analyzeText will currently return null if it is passed an
empty TokenStream, which can lead to a confusing NullPointerException
later on during querying. This commit changes the code to return
NO_INTERVALS instead.
Fixes#42587
We were checking if an exception was caused by a specific reason "Not a
directory". Alas, this reason is locale-dependent and can fail on
systems that are not set to en_US.UTF-8. This commit addresses this by
deriving what the locale-dependent error message would be and using that
for comparison with the actual exception thrown.

We had this as a dependency for legacy dependencies that still needed
the Log4j 1.2 API. This appears to no longer be necessary, so this
commit removes this artifact as a dependency.
To remove this dependency, we had to fix a few places where we were
accidentally relying on Log4j 1.2 instead of Log4j 2 (easy to do, since
both APIs were on the compile-time classpath).
Finally, we can remove our custom Netty logger factory. This was needed
when we were on Log4j 1.2 and handled logging in our own unique
way. When we migrated to Log4j 2 we could have dropped this
dependency. However, even then Netty would still pick up Log4j 1.2 since
it was on the classpath, thus the advantage to removing this as a
dependency now.
Today Elasticsearch does not prevent you from reconfiguring a node's
`path.data` to point to data paths that previously belonged to more than one
node. There's no good reason to be able to do this, and the consequences can be
quietly disastrous. Furthermore, #42489 might result in a user trying to split
up a previously-shared collection of data paths by hand and there's definitely
scope for mixing the paths up across nodes when doing this.
This change adds a check during startup to ensure that each data path belongs
to the same node.
Since the max_score optimization landed in Elasticsearch 7,
the CommonTermsQuery is redundant and slower. Moreover the
cutoff_frequency parameter for MatchQuery and MultiMatchQuery
is redundant.

Today the `LeaderChecker` and `HandshakingTransportAddressConnector` do not log
anything above `DEBUG` level. However there are some situations where it is
appropriate for them to log at a higher level:
- if the low-level handshake succeeds but the high-level one fails then this
indicates a config error that the user should resolve, and the exception
will help them to do so.
- if leader checks fail repeatedly then we restart discovery, and the exception
will help to determine what went wrong.

Refactors the WKT and GeoJSON parsers from an utility class into an
instantiatable objects. This is a preliminary step in
preparation for moving out coordinate validators from Geometry
constructors. This should allow us to make validators plugable.
A disruption test case need to use a lower checkpoint sync interval
since they verify sequence numbers after the test waiting max 10 seconds
for it to stabilize.

* Now that we process the bulk requests themselves on the WRITE threadpool, they can run out of retries too like the item requests even when backoff is active
* Fixes#41324 by using the same logic that checks failed item requests for their retry status for the top level bulk requests as well
When multiple commands are called in sequence, fetch shards
from mutable, up-to-date routing nodes to ensure each command's
changes are visible to subsequent commands.
This addresses an issue uncovered during work on #41050.
The problem this commit addresses is that state recovery is not reset on a node that then becomes
master with a cluster state that has a state not recovered flag in it. The situation that was observed
in a failed test run of MinimumMasterNodesIT.testThreeNodesNoMasterBlock (see below) is that we
have 3 master nodes (node_t0, node_t1, node_t2), two of them are shut down (node_t2 remains),
when the first one comes back (renamed to node_t4) it becomes leader in term 2 and sends state
(with state_not_recovered_block) to node_t2, which accepts. node_t2 becomes leader in term 3, and
as it was previously leader in term1 and successfully completed state recovery, does never retry
state recovery in term 3.

* Make unwrapCorrupt Check Suppressed Ex. (#41889)
* As discussed in #24800 we want to check for suppressed corruption
indicating exceptions here as well to more reliably categorize
corruption related exceptions
* Closes#24800, 41201
* Cleanup Bulk Delete Exception Logging
* Follow up to #41368
* Collect all failed blob deletes and add them to the exception message
* Remove logging of blob name list from caller exception logging
If all primary shards are allocated on the master node, then the
verifying before close step will never interact with mock transport
service. This change prefers to allocate shards on data-only nodes.
Closes#39757
* It looks like we might be cancelling a previous publication instead of
the one triggered by the given request with a very low likelihood.
* Fixed by adding a wait for no in-progress publications
* Also added debug logging that would've identified this problem
* Closes#36813
* Remove Delete Method from BlobStore (#41619)
* The delete method on the blob store was used almost nowhere and just duplicates the delete method on the blob containers
* The fact that it provided for some recursive delete logic (that did not behave the same way on all implementations) was not used and not properly tested either
* Added separate enum for the state of each shard, it was really
confusing that we used the same enum for the state of the snapshot
overall and the state of each individual shard
* relates https://github.com/elastic/elasticsearch/pull/40943#issuecomment-488664150
* Shortened some obvious spots in equals method and saved a few lines
via `computeIfAbsent` to make up for adding 50 new lines to this class
* Remove Obsolete BwC Logic from BlobStoreRepository
* We can't restore 1.3.3 files anyway -> no point in doing the dance of computing a hash here
* Some other minor+obvious cleanups
* Some Cleanup in o.e.i.engine
* Remove dead code and parameters
* Reduce visibility in some obvious spots
* Add missing `assert`s (not that important here since the methods
themselves will probably be dead-code eliminated) but still
If a single pipeline is updated then the internal representation of
all pipelines was updated. With this change, only the internal representation
of the pipelines that have been modified will be updated.
Prior to this change the IngestMetadata of the previous and current cluster
was used to determine whether the internal representation of pipelines
should be updated. If applying the previous cluster state change failed then
subsequent cluster state changes that have no changes to IngestMetadata
will not attempt to update the internal representation of the pipelines.
This commit, changes how the IngestService updates the internal representation
by keeping track of the underlying configuration and use that to detect
against the new IngestMetadata whether a pipeline configuration has been
changed and if so, then the internal pipeline representation will be updated.
We need more information to understand why CcrRetentionLeaseIT is
failing. This commit adds some debug log to retention leases and enables
them in CcrRetentionLeaseIT.
This commit removes the act of renewing some retention leases during a
retention lease recovery test. Having renewal does not add anything
extra to this test, but does allow for some situations where the test
can fail spuriously (i.e., in a way that does not indicate that
production code is broken).
If we close an engine while a refresh is happening, then we might leak
refCount of some SegmentReaders. We need to skip the ram accounting
circuit breaker check until we have a new Lucene snapshot which includes
the fix for LUCENE-8809.
This also adds a test to the engine but left it muted so we won't forget
to reenable this check.
Closes#30290
The shard CLI tool would not do anything if a corruption marker was not
present. But a corruption marker is only added if a corruption is
detected during indexing/writing, not if a search or other read fails.
Changed the tool to always check shards regardless of corruption marker
presence.
