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.

We were checking if an exception was caused by a specific reason "Not a

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

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.

Add support for components used by processor factories to get updated

Components can register via `IngestService#addIngestClusterStateListener(...)`

these components get updated with the current cluster state before
pipelines are updated.
Registered EnrichProcessorFactory as ingest cluster state listener, so
that it has always an up to date view of the active enrich policies.
If all primary shards are allocated on the master node, then the

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.

The shard CLI tool would not do anything if a corruption marker was not

Today the default stabilisation time is calculated on the assumption that the
elected master has no pending tasks to process when it is elected, but this is
not a safe assumption to make. This can result in a cluster reaching the end of
its stabilisation time without having stabilised. Furthermore in #36943 we
increased the probability that each step in `runRandomly()` enqueues another
task, vastly increasing the chance that we hit such a situation.
This change extends the stabilisation process to allow time for all pending
tasks, plus a task that might currently be in flight.
Fixes#41967, in which the master entered the stabilisation phase with over 800
tasks to process.
By default, we track total hits up to 10k but we might index more than

Both of these classes are basically a bloated wrapper around a simple
construct that can simply be a DirectoryFactory interface. This change
removes both classes and replaces them with a simple stateless interface
that creates a new `Directory` per shard. The concept of `index.store` is preserved
since it makes sense from a configuration perspective.
Today the `TransportClusterStateAction` ignores the state passed by the
`TransportMasterNodeAction` and obtains its state from the cluster applier.
This might be inconsistent, showing a different node as the master or maybe
even having no master.

tests showing that the state returned is consistent with our expectations even
if there is a concurrent master failover.

This commit makes creators of GetField split the fields into document fields and metadata fields. It is part of larger refactoring that aims to remove the calls to static methods of MapperService related to metadata fields, as discussed in #24422.
`org.elasticsearch.action.bulk.BulkProcessor` is a threadsafe class that
allows for simple semantics to deal with sending bulk requests. Once a
bulk reaches it's pre-defined size, documents, or flush interval it will
execute sending the bulk. One configurable option is the number of concurrent
outstanding bulk requests. That concurrency is implemented in
`org.elasticsearch.action.bulk.BulkRequestHandler` via a semaphore. However,
the only code that currently calls into this code is blocked by `synchronized`
methods. This results in the in-ability for the BulkProcessor to behave concurrently
despite supporting configurable amounts of concurrent requests.
This change removes the `synchronized` method in favor an explicit
lock around the non-thread safe parts of the method. The call into
`org.elasticsearch.action.bulk.BulkRequestHandler` is no longer blocking, which
allows `org.elasticsearch.action.bulk.BulkRequestHandler` to handle it's own concurrency.
Lucene 8 has the ability to skip blocks of non-competitive documents.
However some queries don't track their maximum score (`script_score`, `span`, ...)
so they always return Float.POSITIVE_INFINITY as maximum score. This can slow down
some boolean queries if other clauses have bounded max scores. This commit disables
the max score optimization when we detect a mandatory scoring clause with unbounded
max scores. Optional clauses are not checked since they can still skip documents
when the unbounded clause is after the current document.
Currently AnalysisRegistry#processNormalizerFactory creates a normalizer and
only later checks whether it should be added to the normalizer map passed in. In
case we throw an exception it isn't closed. This can be prevented by moving the
check that throws the exception earlier.

ShardId already implements Writeable so there is no need for it to implement Streamable too. Also the readShardId static method can be
easily replaced with direct usages of the constructor that takes a
StreamInput as argument.
In case a search request holds only the suggest section, the query phase
is skipped and only the suggest phase is executed instead. There will
never be hits returned, and in case the explain flag is set to true, the
explain sub phase throws a null pointer exception as the query is null.
Usually a null query is replaced with a match all query as part of SearchContext#preProcess which is though skipped as well with suggest
only searches. To address this, we skip the explain sub fetch phase
for search requests that only requested suggestions.

* Remove IndexShard dependency from Repository
In order to simplify repository testing especially for BlobStoreRepository
it's important to remove the dependency on IndexShard and reduce it to
Store and MapperService (in the snapshot case). This significantly reduces
the dependcy footprint for Repository and allows unittesting without starting
nodes or instantiate entire shard instances. This change deprecates the old
method signatures and adds a unittest for FileRepository to show the advantage
of this change.
In addition, the unittesting surfaced a bug where the internal file names that
are private to the repository were used in the recovery stats instead of the
target file names which makes it impossible to relate to the actual lucene files
in the recovery stats.

A shard that is undergoing peer recovery is subject to logging warnings of the form
org.elasticsearch.action.FailedNodeException: Failed node [XYZ]
...
Caused by: org.apache.lucene.index.IndexNotFoundException: no segments* file found in ...
These failures are actually harmless, and expected to happen while a peer recovery is ongoing (i.e.
there is an IndexShard instance, but no proper IndexCommit just yet).
As these failures are currently bubbled up to the master, they cause unnecessary reroutes and
confusion amongst users due to being logged as warnings.

Moves the test infrastructure away from using node.max_local_storage_nodes, allowing us in a
follow-up PR to deprecate this setting in 7.x and to remove it in 8.0.
This also changes the behavior of InternalTestCluster so that starting up nodes will not automatically
reuse data folders of previously stopped nodes. If this behavior is desired, it needs to be explicitly
done by passing the data path from the stopped node to the new node that is started.
Simplifies the voting configuration reconfiguration logic by switching to an explicit Comparator for
the priorities. Does not make changes to the behavior of the component.
Flushing at the end of a peer recovery (if needed) can bring these
benefits:
1. Closing an index won't end up with the red state for a recovering
replica should always be ready for closing whether it performs the
verifying-before-close step or not.
2. Good opportunities to compact store (i.e., flushing and merging
Lucene, and trimming translog)

Today we are persisting the retention leases at least every thirty
seconds by a scheduled background sync. This sync causes an fsync to

commit addresses this by only persisting and fsyncing the retention
leases if they have changed since the last time that we persisted and
fsynced the retention leases.

Downgrading an Elasticsearch node to an earlier version is unsupported, because
we do not make any attempt to guarantee that a node can read any of the on-disk
data written by a future version. Yet today we do not actively prevent
downgrades, and sometimes users will attempt to roll back a failed upgrade with
an in-place downgrade and get into an unrecoverable state.
This change adds the current version of the node to the node metadata file, and
checks the version found in this file against the current version at startup.
If the node cannot be sure of its ability to read the on-disk data then it
refuses to start, preserving any on-disk data in its upgraded state.
This change also adds a command-line tool to overwrite the node metadata file
without performing any version checks, to unsafely bypass these checks and
recover the historical and lenient behaviour.
Secure settings currently error if they exist inside elasticsearch.yml.
This commit adds validation that non-secure settings do not exist inside

The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
If `keyedFilters` is null it assumes there are unkeyed filters...which

Adds an initial limited implementations of geo features to SQL. This implementation is based on the [OpenGIS® Implementation Standard for Geographic information - Simple feature access](http://www.opengeospatial.org/standards/sfs), which is the current standard for GIS system implementation. This effort is concentrate on SQL option AKA ISO 19125-2.
Queries that are supported as a result of this initial implementation
Metadata commands
- `DESCRIBE table` - returns the correct column types `GEOMETRY` for geo shapes and geo points.
- `SHOW FUNCTIONS` - returns a list that includes supported `ST_` functions
- `SYS TYPES` and `SYS COLUMNS` display correct types `GEO_SHAPE` and `GEO_POINT` for geo shapes and geo points accordingly.
Returning geoshapes and geopoints from elasticsearch
- `SELECT geom FROM table` - returns the geoshapes and geo_points as libs/geo objects in JDBC or as WKT strings in console.
- `SELECT ST_AsWKT(geom) FROM table;` and `SELECT ST_AsText(geom) FROM table;`- returns the geoshapes ang geopoints in their WKT representation;
Using geopoints to elasticsearch
- The following functions will be supported for geopoints in queries, sorting and aggregations: `ST_GeomFromText`, `ST_X`, `ST_Y`, `ST_Z`, `ST_GeometryType`, and `ST_Distance`. In most cases when used in queries, sorting and aggregations, these function are translated into script. These functions can be used in the SELECT clause for both geopoints and geoshapes.
- `SELECT * FROM table WHERE ST_Distance(ST_GeomFromText(POINT(1 2), point) < 10;` - returns all records for which `point` is located within 10m from the `POINT(1 2)`. In this case the WHERE clause is translated into a range query.
Limitations:
Geoshapes cannot be used in queries, sorting and aggregations as part of this initial effort. In order to fully take advantage of geoshapes we would need to have access to geoshape doc values, which is coming in #37206. `ST_Z` cannot be used on geopoints in queries, sorting and aggregations since we don't store altitude in geo_point doc values.

This change updates tests that use a CountDownLatch to synchronize the
running of threads when testing concurrent operations so that we ensure
the thread has been fully created and run by the scheduler. Previously,
these tests used a latch with a value of 1 and the test thread counted
down while the threads performing concurrent operations just waited.
This change updates the value of the latch to be 1 + the number of
threads. Each thread counts down and then waits. This means that each
thread has been constructed and has started running. All threads will
have a common start point now.
Today we do not expose the cluster UUID in any logs by default, but it would be
useful to see it. For instance if a user starts multiple nodes as separate
clusters then they will silently remain as separate clusters even if they are

committed cluster UUID the first time the node encounters it.

Currently IndexAnalyzers keeps the three default as separate class members

The changes in #39317 brought to light some concurrency issues in the

address the concurrent close issues but upon review, the closing of
these classes is not really needed as the instances should be become

We have a number of places in analysis-handling code where we check
if a field type is a keyword field, and if so then extract the normalizer rather

by setting the normalizer as the index-time analyzer at construction time.

The close method in Node uses a StopWatch to time to closing of

`discovery.seed_hosts` setting:
```
discovery.seed_hosts: 10.1.2.3:9300-9400
```
Silently ignoring part of a setting like this is trappy. With this change we
reject seed host addresses of this form.
Closes#40786
Backport of #41404
Today if an exception is thrown when serializing a cluster state during
publication then the master enters a poisoned state where it cannot publish any
more cluster states, but nor does it stand down as master, yielding repeated
exceptions of the following form:
```

This is because it already created the publication request using
`CoordinationState#handleClientValue()` but then it fails before accepting it.
This commit addresses this by performing the serialization before calling
`handleClientValue()`.
Relates #41090, which was the source of such a serialization exception.
The fractional seconds portion of strict_date_optional_time was
accidentally copied from the printer, which always prints at least 3
fractional digits. This commit fixes the formatter to allow 1 or 2
fractional seconds.
closes#41633
Add a test that stresses concurrent writes using ifSeqno/ifPrimaryTerm to do CAS style updates. Use linearizability checker to verify linearizability. Linearizability of successful CAS'es is guaranteed.
Changed linearizability checker to allow collecting history concurrently.
Changed unresponsive network simulation to wake up immediately when network disruption is cleared to ensure tests proceed in a timely manner (and this also seems more likely to provoke issues).
Full text queries that start with now are not cacheable if they target a date field.
However we assume in the query builder tests that all queries are cacheable and this assumption
fails when the random generated query string starts with "now". This fails twice in several years
since the probability that a random string starts with "now" is low but this commit ensures that
isCacheable is correctly checked for full text queries that fall into this edge case.
