When trying to add a setting to the keystore with an upper case name, we
reject with an unclear error message. This commit makes that error
message much clearer.
These docs are out of date, now that we override the infinite DNS cache
within Elasticsearch. This commit completely removes this content, as
specific guidance is no longer needed here.
This commit sets the BWC projects to build in parallel if Gradle was
invoked with parallal project execution enabled. This substantially
speeds up the time of building the BWC projects since there are many
dependent projects needed to build a BWC version.
* Don't Ping on Handshake Connection
* It does not make sense to run pings on the handshake connection
* Set the ping interval to `-1` to deactivate pings on it
* A few warnings could be observed in test logs about `NoSuchElementException` being thrown in `InboundChannelBuffer#sliceBuffersTo`.
These were the result of calls to this method after the relevant channel and hence the buffer was closed already as a result of a failed IO operation.
* Fixed by adding the necessary guard statements to break out in these cases. I don't think there is a need here to do any additional error handling since `eventHandler.postHandling(channelContext);` at the end of the `processKey`
call in the main selection loop handles closing channels and invoking callbacks for writes that failed to go through already.
The ScheduledEvent class has never preserved the time
zone so it makes more sense for it to store the start and
end time using Instant rather than ZonedDateTime.
Closes#38620
Today the abstract `org.elasticsearch.discovery.PeerFinder` uses the logger of
its implementation, which in production is in `o.e.cluster.coordination`. This
turns out to be confusing and unhelpful, so with this change we move to using
the logger that belongs to `PeerFinder`.
* Add "columnar" option for REST requests (but be lenient for non-"plain"
modes) for json, yaml, smile and cbor formats.
* Updated documentation

Packaging tests did not honor bwc tests being off.
This was also the reason for which we were building the BWC versinons
even if the tests are off, so this closes#35347.
Currently there are two security tests that specifically target the
netty security transport. This PR moves the client authentication tests
into `AbstractSimpleSecurityTransportTestCase` so that the nio transport
will also be tested.
Additionally the work to build transport configurations is moved out of
the netty transport and tested independently.
This changes the name of the internal security index to ".security-7",
but supports indices that were upgraded from earlier versions and use
the ".security-6" name.
In all cases, both ".security-6" and ".security-7" are considered to
be restricted index names regardless of which name is actually in use
on the cluster.
Backport of: #39337
Some small fix for the `x-pack` rest api spec.
* In both `security.enable_user.json` and `security.disable_user.json`
the `username` parameter was `false` instead of `true`
(the documentation is already correct).
* In `security.get_privileges.json` there were missing all the
possible paths since the path parameters are not required.
This fix aligns the document with the rest of the spec,
where all the possible combinations are listed.
It is possible that the Unfollow API may fail to release shard history
retention leases when unfollowing, so this needs to be handled by the
ILM Unfollow action. There's nothing much that can be done automatically
about it from the follower side, so this change makes the ILM unfollow
action simply ignore those failures.
Since #39006, we should either remove `testWaitForPendingSeqNo`
or adjust it not to wait for the pending operations. This change picks
the latter.

`withLocalReduction` is confusing as `local` effectively means "local
to the remote clusters" rather than "local the coordinating node" where
the method is executed. I propose we rename the method to
`crossClusterSearch` which better resembles what the static method is
used for.
While running these commands from alias, facing issues using kill `cat pid`, In some situations, the more compact:
```
pkill -F /var/run/myProcess.pid
```
is the way to go.
We have been calling `reduce` against completion suggestions twice, once
in `SearchPhaseController#reducedQueryPhase` where all suggestions get
reduced, and once more in `SearchPhaseController#sortDocs` where we
add the top completion suggestions to the `TopDocs` so their docs can
be fetched. There is no need to do reduction twice. All suggestions can
be reduced in one call, then we can filter the result and pass only the
already reduced completion suggestions over to `sortDocs`. The small
important detail is that `shardIndex`, which is currently used only
to fetch suggestions hits, needs to be set before the first reduction,
hence outside of `sortDocs` where we have been doing it until now.
This change is a backport of #39252
- Fixes TokenBackwardsCompatibilityIT: Existing tests seemed to made
the assumption that in the oneThirdUpgraded stage the master node
will be on the old version and in the twoThirdsUpgraded stage, the
master node will be one of the upgraded ones. However, there is no
guarantee that the master node in any of the states will or will
not be one of the upgraded ones.
This class now tests:
- That we can generate and consume tokens before we start the
rolling upgrade.
- That we can consume tokens generated in the old cluster during
all the stages of the rolling upgrade.
- That while on a mixed cluster, when/if the master node is
upgraded, we can generate, consume and refresh a token
- That after the rolling upgrade, we can consume a token
generated in an old cluster and can invalidate it so that it
can't be used any more.
- Ensures that during the rolling upgrade, the upgraded nodes have
the same configuration as the old nodes. Specifically that the
file realm we use is explicitly named `file1`. This is needed
because while attempting to refresh a token in a mixed cluster
we might create a token hitting an old node and attempt to refresh
it hitting a new node. If the file realm name is not the same, the
refresh will be seen as being made by a "different" client, and
will, thus, fail.
- Renames the Authentication variable we check while refreshing a
token to be clientAuth in order to make the code more readable.
Some of the above were possibly causing the flakiness of #37379
Checks that the core coordination algorithm implemented as part of Zen2 (#32006) supports
linearizable semantics. This commit adds a linearizability checker based on the Wing and Gong
graph search algorithm with support for compositional checking and activates these checks for all
CoordinatorTests.
Today we do not bubble up exceptions when processing NoOps but always
treat them as document-level failures. This incorrect treatment causes
the assert_no_failure being tripped in peer-recovery if IndexWriter was
closed exceptionally before.
Closes#38898
Today when users upgrade to 7.0, existing indices will automatically
switch to soft-deletes without an opt-out option. With this change,
we only enable soft-deletes by default for new indices.

This commit is the final piece of the integration of CCR with retention
leases. Namely, we periodically renew retention leases and advance the
retaining sequence number while following.
* Remove Hipchat support from Watcher (#39199)
Hipchat has been shut down and has previously been deprecated in
Watcher (#39160), therefore we should remove support for these actions.
* Add migrate note
Moves the check for tiny polygons earlier in the test. It turned out
that polygons can be so tiny that we cannot even figure out their
orientation.

* Set mappings when creating indices in SuggestSearchIT
These tests don't test dynamic mapping, so they can use preset mappings. This
removes the possibility they may fail due to the mapping not being available
since mapping updates are asynchronous.

This fixes a bug in the sensing of the current OS family in the test cluster
formation code. Previously all builds would assume every environment
was windows and would jump to using the windows zip build. This fixes
the OS sensing code as well as updates some tests to account for
different build flavors.
Backport of #38457
With this change, we won't wait for the local checkpoint to advance to
the max_seq_no before starting phase2 of peer-recovery. We also remove
the sequence number range check in peer-recovery. We can safely do these
thanks to Yannick's finding.
The replication group to be used is currently sampled after indexing
into the primary (see `ReplicationOperation` class). This means that
when initiating tracking of a new replica, we have to consider the
following two cases:
- There are operations for which the replication group has not been
sampled yet. As we initiated the new replica as tracking, we know that
those operations will be replicated to the new replica and follow the
typical replication group semantics (e.g. marked as stale when
unavailable).
- There are operations for which the replication group has already been
sampled. These operations will not be sent to the new replica. However,
we know that those operations are already indexed into Lucene and the
translog on the primary, as the sampling is happening after that. This
means that by taking a snapshot of Lucene or the translog, we will be
getting those ops as well. What we cannot guarantee anymore is that all
ops up to `endingSeqNo` are available in the snapshot (i.e. also see
comment in `RecoverySourceHandler` saying `We need to wait for all
operations up to the current max to complete, otherwise we can not
guarantee that all operations in the required range will be available
for replaying from the translog of the source.`). This is not needed,
though, as we can no longer guarantee that max seq no == local
checkpoint.

Today this test catches an exception and asserts that its proximate cause has
message `Random IOException` but occasionally this exception is wrapped two
layers deep, causing the test to fail. This commit adjusts the test to look at
the root cause of the exception instead.

In integration tests where `setBootstrapMasterNodeIndex()` is used in
combination with `autoMinMasterNodes = false` the cluster can start
bootstrapping once the number of nodes set with the
`setBootstrapMasterNodeIndex` have been started but it's not ensured
that all nodes have successfully joined to form the cluster.
This behaviour was introduced with 5db7ed22a0
and in order to ensure that the cluster is properly formed before proceeding
with the integration test, use `ensureStableCluster()` with the
appropriate number of expected nodes.
Fixes: #39220
In #39224 we made shard history retention lease syncing ignore the
`index.write.wait_for_active_shards` setting on the index, and added a test
that showed that it was ignored. However the test as merged actually creates a
green index, so the `wait_for_active_shards` setting has no effect. This change
adjusts the test to create a yellow index to verify that
`wait_for_active_shards` really is ignored.
when dealing with TimeoutException
The `IndexFollowingIT#testDeleteLeaderIndex()`` test failed,
because a NPE was captured as fatal error instead of an IndexNotFoundException.
