Currently, there are a few tests that use autoMinMasterNodes=false and
hence override addExtraClusterBootstrapSettings, mostly this is 10-30
lines of codes that are copy-pasted from class to class.
This PR introduces `InternalTestCluster.setBootstrapMasterNodeIndex`
which is suitable for all classes and copy-paste could be removed.
Removing code is always a good thing!
This test failed once because the index wasn't fully ready
(ie, engine opened). This commit changes the test so that
it waits for the index to be green before checking the history
UUID.
Closes#34452
The terms aggregator loads the global ordinals to retrieve the cardinality of the field to aggregate on. This information is then used to select the strategy to use for the aggregation (breadth_first or depth_first). However this should be avoided if the execution_hint is explicitly set to map since this mode doesn't really need the global ordinals. Since we still need the cardinality of the field this change picks the maximum cardinality in the segments as an estimation of the total cardinality to select the strategy to use (breadth_first or depth_first). This estimation is only used if the execution hint is set to map, otherwise the global ordinals are still used to retrieve the accurate cardinality.
Closes#37705
Today we use `AbstractDisruptionTestCase` to test the behaviour of things like
master elections in the presence of cluster disruptions. These tests have
rather enthusiastic fault detection settings, detecting a fault if a single
ping fails, with a one-second timeout. Furthermore there are some tests that
assert the identity of the master remains unchanged during some disruption, and
these assertions fail rather often thanks to the overly sensitive fault
detector.
However in a number of these tests the fault detector need not be this
sensitive. This commit moves some such tests into their own test suite and uses
more sensible fault-detection settings to avoid the kind of master instability
that is causing CI failures.
Closes#37699
The self written epoch date formatters were not properly able to format
an Instant to a string due to a misconfiguration.
This fix also removes a until now existing runtime behaviour under java
8 regarding the names of the aggregation buckets, which are now the same
as before and have been under java 11.
The '{' as a first character in log line is causing problems for beats when parsing plaintext logs. This can happen if the submitted document has an additional '\n' at the beginning and we are not reformatting.
Trimming the source part of a SlogLog solves that and keeps the logs readable.

In 6.3 trial licenses were changed to default to security
disabled, and ee added some heuristics to detect when security should
be automatically be enabled if `xpack.security.enabled` was not set.
This change removes those heuristics, and requires that security be
explicitly enabled (via the `xpack.security.enabled` setting) for
trial licenses.

* Fixes two broken spots:
1. Master failover while deleting a snapshot that has no shards will get stuck if the new master finds the 0-shard snapshot in `INIT` when deleting
2. Aborted shards that were never seen in `INIT` state by the `SnapshotsShardService` will not be notified as failed, leading to the snapshot staying in `ABORTED` state and never getting deleted with one or more shards stuck in `ABORTED` state
* Tried to make fixes as short as possible so we can backport to `6.x` with the least amount of risk
* Significantly extended test infrastructure to reproduce the above two issues
* Two new test runs:
1. Reproducing the effects of node disconnects/restarts in isolation
2. Reproducing the effects of disconnects/restarts in parallel with shard relocations and deletes
* Relates #32265
* Closes#32348
Since #31140 we no longer require acking on the dynamic mapping of index
requests. Thus, a returned mapping from a get mapping request does not
necessarily contain the dynamic updates from the index request. This
commit replaces the dynamic mapping update with a manual put mapping.

Currently we use the raw byte array length when calling the IndexInput
read call to determine how many bytes we want to read. However, due to
how BigArrays works, the array length might be longer than the reference
length. This commit fixes the issue and uses the BytesRef length when
calling read. Additionally, it expands the index follow test to index
many more documents. These documents should potentially lead to large
enough segment files to trigger scenarios where this fix matters.
This changes the test to not use a `CountDownlatch`, instead adding an assertion
for the final logging message and waiting until the `MockAppender` has seen it
before proceeding.

Resolves#23739
Implements `geotile_grid` aggregation
This patch refactors previous implementation https://github.com/elastic/elasticsearch/pull/30240
This code uses the same base classes as `geohash_grid` agg, but uses a different hashing
algorithm to allow zoom consistency. Each grid bucket is aligned to Web Mercator tiles.
When the ingest node user agent parses the device field, it
will result in a string value. To match the ecs schema
this commit moves the value of the parsed device to an
object with an inner field named 'name'. There are not
any passivity concerns since this modifies an unreleased change.

If a replica does not have a right mapping yet, we will retry the index
request on that replica; then the actual tasks is higher than the
expected tasks. Since #31140 this happens more frequently for we no
longer require acking on the dynamic mapping of index requests.

Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a
scheduled Runnable is logged as a warning.
This is a continuation of #28667, #36137 and also fixes#37708.
This commit adapts the version used in StartedShardEntry serialization

FIRST and LAST can be used with one argument and work similarly to MIN
and MAX but they are implemented using a Top Hits aggregation and
therefore can also operate on keyword fields. When a second argument is
provided then they return the first/last value of the first arg when its
values are ordered ascending/descending (respectively) by the values of
the second argument. Currently because of the usage of a Top Hits
aggregation FIRST and LAST cannot be used in the HAVING clause of a
GROUP BY query to filter on the results of the aggregation.
Closes: #35639
This commit pushes the primary term into the replication tracker. This
is a precursor to using the primary term to resolving ordering problems
for retention leases. Namely, it can be that out-of-order retention
lease sync requests arrive on a replica. To resolve this, we need a
tuple of (primary term, version). For this to be, the primary term needs
to be accessible in the replication tracker. As the primary term is part
of the replication group anyway, this change conceptually makes sense.
With #37566 we have introduced the ability to merge multiple search responses into one. That makes it possible to expose a new way of executing cross-cluster search requests, that makes CCS much faster whenever there is network latency between the CCS coordinating node and the remote clusters. The coordinating node can now send a single search request to each remote cluster, which gets reduced by each one of them. from + size results are requested to each cluster, and the reduce phase in each cluster is non final (meaning that buckets are not pruned and pipeline aggs are not executed). The CCS coordinating node performs an additional, final reduction, which produces one search response out of the multiple responses received from the different clusters.
This new execution path will be activated by default for any CCS request unless a scroll is provided or inner hits are requested as part of field collapsing. The search API accepts now a new parameter called ccs_minimize_roundtrips that allows to opt-out of the default behaviour.

This reduces objects creations in the rounding class (used by aggs) by properly
creating the objects only once. Furthermore a few unneeded ZonedDateTime objects
were created in order to create other objects out of them. This was
changed as well.
Running the benchmarks shows a much faster performance for all of the
java time based Rounding classes.
Currently the put-mapping API assumes that because the type name is `_doc` then
it is dealing with a typeless put-mapping call. Yet we still allow running the
put-mapping API in a typed fashion with `_doc` as a type name. The current logic
triggers surprising errors when doing a typed put-mapping call with `_doc` as a
type name on an index that has a type already.
This is a bit of a corner-case, but is more important on 6.x due to the fact
that using the index API with `_doc` as a type name triggers typed calls to the
put-mapping API with `_doc` as a type name.
* Added SSL configuration options tests
Removed the allow.self.signed option from the documentation since we allow
by default self signed certificates as well.
