We should be consistent here. We were already using the casing "Ccr" and
this is the preferred casing for Java class names. This commit adjusts
the names of some classes that were using the casing "CCR" to be "Ccr".
In the docs tests, we have pre-defined setups in the build.gradle file,
and we can also define test setup sections within the doc page
itself. Alas, these two are incompatible in that if you try to use a
pre-defined setup alongside a test setup section, the pre-defined setup
will be silently ignored. This commit enables pre-defined setup sections
to be used together with test setup sections. The ordering here is that
pre-defined setup sections will be executed first, followed by the test
setup section.
In some of our X-Pack REST tests we have to wait for pending tasks to
complete. We are now needing this functionality in ESRestTestCase for
the docs tests where we run against X-Pack features. This commit moves
the helper method that we have in X-Pack to ESRestTestCase, and removes
duplicate logic from waiting for rollup tasks to complete.
This commit switches to using a trial license in the docs tests that run
on the default distribution. This is needed so that docs tests can be
executed against non-basic features.
This change introduces stats per processors. Total, time, failed,
current are currently supported. All pipelines will now show all
top level processors that belong to it. Failure processors are not
displayed, however, the time taken to execute the failure chain is part
of the stats for the top level processor.
The processor name is the type of the processor, ordered as defined in
the pipeline. If a tag for the processor is found, then the tag is
appended to the type.
Pipeline processors will have the pipeline name appended to the name of
the name of the processors (before the tag if one exists). If more
then one pipeline is used to process the document, then each pipeline
will carry its own stats. The outer most pipeline will also include the
inner most pipeline stats.
Conditional processors will only included in the stats if the condition evaluates
to true.
After we bumped the JDK compiler minimum requirements to JDK 11, we
missed updating the contributing docs to point to JDK 11 instead of JDK
10. This commit fixes that.
Additionally, when we stopped requiring JDK 7 to run the reindex from
old tests, we did not update the contributing docs to reflect this. This
commit also fixes that.
With remote clusters taking on a larger role, we have make the
infrastructure more generic than being tied to cross-cluster search
(CCS). We want to refer to the remote clusters configuration in the
cross-cluster replication (CCR) docs. Yet, these docs are still tied to
CCS. This commit extracts the remote clusters docs from CCS (with some
wording changes to make them more general) so that we can refer to them
in the CCR docs.
Since #34288, we might hit deadlock if the FollowTask has more fetchers
than writers. This can happen in the following scenario:
Suppose the leader has two operations [seq#0, seq#1]; the FollowTask has
two fetchers and one writer.
1. The FollowTask issues two concurrent fetch requests: {from_seq_no: 0,
num_ops:1} and {from_seq_no: 1, num_ops:1} to read seq#0 and seq#1
respectively.
2. The second request which fetches seq#1 completes before, and then it
triggers a write request containing only seq#1.
3. The primary of a follower fails after it has replicated seq#1 to
replicas.
4. Since the old primary did not respond, the FollowTask issues another
write request containing seq#1 (resend the previous write request).
5. The new primary has seq#1 already; thus it won't replicate seq#1 to
replicas but will wait for the global checkpoint to advance at least
seq#1.
The problem is that the FollowTask has only one writer and that writer
is waiting for seq#0 which won't be delivered until the writer completed.
This PR proposes to replicate existing operations with the old primary
term (instead of the current term) on the follower. In particular, when
the following primary detects that it has processed an process already,
it will look up the term of an existing operation with the same seq_no
in the Lucene index, then rewrite that operation with the old term
before replicating it to the following replicas. This approach is
wait-free but requires soft-deletes on the follower.

Fixes#34418
The shard suggestion sort uses a different tie-break than the one that is used
to merge different shards responses. The former uses the internal document identifier
when scores are the same whereas the latter compares the surface form first.
Because of this discrepancy some suggestion outputs are linked to the wrong documents
because the merge sort reorders the shard suggestions differently. This change
fixes this bug by duplicating the Lucene collector in order to be able to apply the
same tiebreak strategy than the merge sort. This logic will be removed when
https://issues.apache.org/jira/browse/LUCENE-8529 is fixed.
Closes#34378
Today we rely on the LocalCheckpointTracker to ensure no duplicate when
enabling optimization using max_seq_no_of_updates. The problem is that
the LocalCheckpointTracker is not fully reloaded when opening an engine
with an out-of-order index commit. Suppose the starting commit has seq#0
and seq#2, then the current LocalCheckpointTracker would return "false"
when asking if seq#2 was processed before although seq#2 in the commit.
This change scans the existing sequence numbers in the starting commit,
then marks these as completed in the LocalCheckpointTracker to ensure
the consistent state between LocalCheckpointTracker and Lucene commit.

Fix#32079
Exclusion setting `cluster.routing.allocation.exclude._host` default value
is an empty string.
When an exclusion setting is sent with a null value the
o.e.c.s.Setting#innerGetRaw API return an empty string (probably to
avoid a NullPointerException to be raised).
The o.e.c.r.a.d.FilterAllocationDecider class is developed to omit
updates of default values for exclusion setting.
That's why a null exclusion setting value is translated to an empty
string which is equals to the exclusion default value which is
configured to be ignored.
A simple fix would be to not omit default values for exclusion setting
and keep the NullPointerException guard. This is the purpose of this
commit.
Closes#32721
The `term` and `phrase` suggesters have different options to filter candidates
based on their frequencies. The `popular` mode for instance filters candidate
terms that occur in less docs than the original term. However when we compute this threshold
we use the total term frequency of a term instead of the document frequency. This is not inline
with the actual filtering which is always based on the document frequency. This change fixes
this discrepancy and clarifies the meaning of the different frequencies in use in the suggesters.
It also ensures that the threshold doesn't overflow the maximum allowed value (Integer.MAX_VALUE).
Closes#34282
Currently the StemmerTokenFilterFactory checks the validity of the language
setting only when the first TokenStream is processed. Instead we should throw an
error earlier at mapping creation time. This change adds a check to the
StemmerTokenFilterFactory constructor that checks for a valid `language` setting
by trying to create a new TokenStream from an empty input stream. This will
throw errors about wrong language settings early on.
