With this change, shard allocation prefers allocating replicas on a node
that already has a copy of the shard that is as close as possible to the
primary, so that it is as cheap as possible to bring the new replica in
sync with the primary. Furthermore, if we find a copy that is identical
to the primary then we cancel an ongoing recovery because the new copy
which is identical to the primary needs no work to recover as a replica.
We no longer need to perform a synced flush before performing a rolling
upgrade or full cluster start with this improvement.
Closes#46318
This change should reduce refreshes for a use-case where we perform
multiple realtime gets at the same time on an active index. Currently,
we only call refresh if the index operation is still on the versionMap.
However, at the time we call refresh, that operation might be already or
will be included in the latest reader. Hence, we do not need to refresh.
Adding another lock here is not an issue as the refresh is already
sequential.
If we roll translog but do not index, then a flush without force is a
noop. In this case, the number of retained translog files will be higher
than the value specified by the retention policy.
Closes#4741
Usually syslog timestamps have two spaces before a single
digit day-of-month. However, in some non-syslog cases
where syslog-like timestamps are used there is only one
space. The grok pattern supports this, so the timestamp
parser should too. This change makes the
find_file_structure endpoint do this.
Also fixes another problem that the same test case
exposed in the find_file_structure endpoint, which was
that the exclude_lines_pattern for delimited files was
always created on the assumption the delimiter was a
comma. Now it is based on the actual delimiter.
This commit adds two APIs that allow to pause and resume
CCR auto-follower patterns:
// pause auto-follower
POST /_ccr/auto_follow/my_pattern/pause
// resume auto-follower
POST /_ccr/auto_follow/my_pattern/resume
The ability to pause and resume auto-follow patterns can be
useful in some situations, including the rolling upgrades of
cluster using a bi-directional cross-cluster replication scheme
(see #46665).
This commit adds a new active flag to the AutoFollowPattern
and adapts the AutoCoordinator and AutoFollower classes so
that it stops to fetch remote's cluster state when all auto-follow
patterns associate to the remote cluster are paused.
When an auto-follower is paused, remote indices that match the
pattern are just ignored: they are not added to the pattern's
followed indices uids list that is maintained in the local cluster
state. This way, when the auto-follow pattern is resumed the
indices created in the remote cluster in the meantime will be
picked up again and added as new following indices. Indices
created and then deleted in the remote cluster will be ignored
as they won't be seen at all by the auto-follower pattern at
resume time.
Backport of #47510 for 7.x
Previously, Nullability was set to UNKNOWN instead of TRUE which
resulted on QueryFolder not correctly folding to NULL if any of the args
was null.
Remove the overriding nullable() also for DatePart/DateTrunc to allow
delegation the parent class.

The distribution download plugin which handles finding built
distributions for testing currently only knows how to find locally built
snapshots. When an external Elasticsearch plugin uses build-tools, these
snapshots do not exist. This commit extends the download plugin so it
pulls from the Elastic snapshots service when used outside of the
Elasticsearch repository.

Joda was using ResolverStyle.STRICT when parsing. This means that date will be validated to be a correct year, year-of-month, day-of-month
However, we also want to make it works with Year-Of-Era as Joda used to, hence custom temporalquery.localdate in DateFormatters.from
Within DateFormatters we use the correct uuuu year instead of yyyy year of era
worth noting: if yyyy(without an era) is used in code, the parsing result will be a TemporalAccessor which will fail to be converted into LocalDate. We mostly use DateFormatters.from so this takes care of this. If possible the uuuu format should be used.
* [ML][Analytics] fix bug where regression deleted early does not delete state (#47885)
* [ML][Analytics] fix bug where regression deleted early does not delete state
* Fixing ml with security test failure
* fixing for older java
* GlobalBuildInfo plugin searches packed references
In recent versions of Git, references may be packed in a packed-refs
file. If this happens, Gradle will need to look in that file to find
build information.
We fixed warnings related to task input and outputs in #45098.
This particular input was not considered, a warning was present for it
and Gradle didn't use it as part of task inputs.
As soon as we fixed it Gradle started considering it an input and
enforced that it exists.
With this change we make it optional as the task can work both wih and
without this directory.
Today the `elasticsearch-shard remove-corrupted-data` tool will only truncate a
translog it determines to be corrupt. However there may be other cases in which
it is desirable to truncate the translog, for instance if an operation in the
translog cannot be replayed for some reason other than corruption. This commit
adds a `--truncate-clean-translog` option to skip the corruption check on the
translog and blindly truncate it.
This change adds documentation for the SAML APIs in Elasticsearch
and adds simple instructions on how these APIs can be used to
authenticate a user with SAML by a custom web application other
than Kibana.
Resolves: #40352
Shrink would set `max_retries=1` in order to avoid retrying. This
however sticks to the shrunk index afterwards, causing issues when a
shard copy later fails to allocate just once.
Avoiding a retry of a shrink makes sense since there is no new node
to allocate to and a retry will likely fail again. However, the downside of
having max_retries=1 afterwards outweigh the benefit of not retrying
the failed shrink a few times. This change ensures shrink no longer
sets max_retries and also makes all resize operations (shrink, clone,
split) leave the setting at default value rather than copy it from source.
rename internal indexes of transform plugin
- rename audit index and create an alias for accessing it, BWC: add an alias for old indexes to
keep them working, kibana UI will switch to use the read alias
- rename config index and provide BWC to read from old and new ones
Enable partial parsing of date part. This is making the behaviour in java.time implementation the same as with joda.
2018, 2018-01 and 2018-01-01 are all valid dates for date_optional_time or strict_date_optional_time

Batch transforms automatically stop after all data has processed, therefore tests can not reliable test the state. This change rewrites tests to remove the unreliable tests or use continuous transforms instead as they do not auto-stop.

One of the tests in this suit stops a master node,
plus we're doing other node starts in this suit.
=> the internal test cluster should be TEST and not `SUITE`
scoped to avoid random failures like the one in #47834Closes#47834
SiblingPipelineAggregator is a public interfaces,
but the ctor was package-private. These should be protected so that
plugin authors can extend and implement their own sibling pipeline agg.
The random timestamps were landing too close to the current time,
so an unlucky rollup interval would round such that the doc wasn't
included in the search range (and thus not "rolled up") which
would then fail the test.
The fix is to make sure the timestamp of all docs is sufficiently behind
'now' that the possible rounding intervals will always include them.
Backport of #38753 to 7.x where the test was still muted.
Refactor DateTrunc and DatePart to use separate Pipe classes which
allows the removal of the BinaryDateOperation enum.

Clarifies not to set `cluster.initial_master_nodes` on nodes that are joining

Today built-in highlighter and plugins have access to the SearchContext through the
highlighter context. However most of the information exposed in the SearchContext are not needed and a QueryShardContext
would be enough to perform highlighting. This change replaces the SearchContext by the informations that are absolutely
required by highlighter: a QueryShardContext and the SearchContextHighlight. This change allows to reduce the exposure of the
complex SearchContext and remove the needs to clone it in the percolator sub phase.
