Adding logging to confirm the suspicion that there might be another old index
lingering around in the test cluster in cases where this test occasionally
fails.
Added helper methods to ESRestTestCase for checking warnings in mixed and current-version-only clusters.
This is supported by a new VersionSpecificWarningsHandler class with associated unit test.
Closes#36251
Today the Zen2 coordinator only applies a write block when there is no known
elected master, ignoring the `discovery.zen.no_master_block` setting. This
commit resolves this, applying the correct block according to the configuration
instead.
Today we do not enforce soft-deletes when accessing the Lucene changes
snapshot. This might lead to internal errors because we assume
soft-deletes are enabled in that code path.
1. CCR tests work without any changes
2. `testDanglingIndices` require changes the source code (added TODO).
3. `testIndexDeletionWhenNodeRejoins` because it's using just two
nodes, adding the node to exclusions is needed on restart.
4. `testCorruptTranslogTruncationOfReplica` starts dedicated master
one, because otherwise, the cluster does not form, if nodes are stopped
and one node is started back.
5. `testResolvePath` needs TEST cluster, because all nodes are stopped
at the end of the test and it's not possible to perform checks needed
by SUITE cluster.
6. `SnapshotDisruptionIT`. Without changes, the test fails because Zen2
retries snapshot creation as soon as network partition heals. This
results into the race between creating snapshot and test cleanup logic
(deleting index). Zen1 on the
other hand, also schedules retry, but it takes some time after network
partition heals, so cleanup logic executes latter and test passes. The
check that snapshot is eventually created is added to
the end of the test.
This adds tests for each possible cast of def to a primitive type both implicit
and explicit. This also fixes a minor bug where we were only checking the type
of a def to be Number in some explicit casts. This does not work because it
allows possible unintended casts from BigInteger and BigDecimal to primitive
types since they both extend Number but are not included as part of the
Painless casting model.
Adds a setting that indicates that an index is done indexing, set by ILM
when the Rollover action completes. This indicates that the Rollover
action should be skipped in any future invocations, as long as the index
is no longer the write index for its alias.
This enables 1) an index with a policy that involves the Rollover action
to have the policy removed and switched to another one without use of
the move-to-step API, and 2) integrations with Beats and CCR.
This commit adds Zulu to the CI rotation. This commit only means that we
are going to try running CI against Zulu, it does not carry any
implications of support in the past, now, or in the future.
Today we log a slightly cryptic "cluster bootstrapping is disabled on this
node" message if bootstrapping hasn't been configured. Since there is today
only one way to bootstrap the cluster it seems preferable to spell out exactly
which setting is missing.
* Lower fielddata circuit breaker default limit
Lower fielddata circuit breaker default limit from 60% to 40% as we have
moved to doc_values for most of the cases.
* merge master in
* update tests
* update docs
Deals with a situation where a follower becomes disconnected from the leader, but only for such a
short time where it becomes candidate and puts up a NO_MASTER_BLOCK, but then receives a
follower check from the leader. If the leader does not notice the node disconnecting, it is important
for the node not to be turned back into a follower but try and join the leader again.
We still should prefer the node into a follower on a follower check when this follower check triggers
a term bump as this can help during a leader election to quickly have a leader turn all other nodes
into followers, even before the leader has had the chance to transfer a possibly very large cluster
state.
Closes#36428
* This commit is part of our plan to deprecate and ultimately remove the use of _xpack in the REST APIs.
- REST API docs
- HLRC docs and doc tests
- Handle REST actions with deprecation warnings
- Changed endpoints in rest-api-spec and relevant file names
Bulk requests comprise many individual actions, and the responses for each
action comes back in the same order (see e.g. `DocumentActionsIT#testBulk()`).
However the docs do not seem to explicitly state this vital fact. This commit
addresses that omission.
The following updates were made:
- Add a new untyped endpoint `{index}/_explain/{id}`.
- Add deprecation warnings to Rest*Action, plus tests in Rest*ActionTests.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
This commit converts the watcher execution context to use the joda
compat java time objects. It also again removes the joda methods from
the painless whitelist.
For each API, the following updates were made:
- Add deprecation warnings to `Rest*Action`, plus tests in `Rest*ActionTests`.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
This commit changes the Docker assemble tasks so that they attempt to
build Docker if the Docker binaries exist, of if build.docker is set to
true. If the Docker binaries do not exist, or if build.docker is set to
false, then no attempt is made to build the Docker images.
The transport client was linking to a page in maven central that didn't
have the transport client in it. This is better link and happens to be
the same link that the low and high level rest client use.
Allow `auto_date_histogram` as a valid parent agg for derivative,
cumulative sum, moving average, moving function and serial
differencing pipeline aggregations.
Since all these aggs share the same requirement (sequentially
ordered parent aggs), this commit also refactors to share
the same validation code so that any newly added aggs won't
be forgotten.
Closes#35578
* Add non-X-Pack centric rollup endpoints
This commit adds new endpoints for rollup that do not have _xpack in
their path. The purpose for this change is to take these endpoints into
6.x as well so that they can be available in mixed cluster tests too. A
follow-up change will deprecate the use of _xpack in the rollup
endpoints. And finally, in the future, we would remove the _xpack
endpoints.
* Remove import
* Fix typo
This change adds a way to provide the content type of the rest serialization
tests when creating random instances. This is used by SearchHitsTests to ensure
that the internal members of the class are created with the same xContentType
and that equals can be used to compare an instances created from an XContent
view.
Today the `GetDiscoveredNodesAction` waits, possibly indefinitely, to discover
enough nodes to bootstrap the cluster. However it is possible that the cluster
forms before a node has discovered the expected collection of nodes, in which
case the action will wait indefinitely despite the fact that it is no longer
required.
This commit changes the behaviour so that the action fails once a node receives
a cluster state with a nonempty configuration, indicating that the cluster has
been successfully bootstrapped and therefore the `GetDiscoveredNodesAction`
need wait no longer.
Relates #36380 and #36381; reverts 558f4ec278.
Previously, we used a CamelCase to CAMEL_CASE transformation to get the
primary name of a function from its class name which led to some issues
since there are functions that we don't want to be registered this way
(e.g.: IFNULL). To simplify the logic and avoid and "magic"
transformations in the FunctionRegistry a primary name must be provided
explicitely for each function.
The same change is applied for the function resolution (when a function
is used in an SQL statement). There is no CamelCase to CAMEL_CASE
transformation but only upper-casing is applied (fuNcTiOn -> FUNCTION).
This commit adds support for the index templates exist API, creating
new client-side request types for that API and the get index
templates API. Also adds links in hlrc docs to pages for supported
index template APIs
This commit creates JodaDateFormatter to replace
FormatDateTimeFormatter. It converts all uses of the old class
to DateFormatter to allow a future change to use JavaDateFormatter
when appropriate.
This allows you to plug the behavior that the LLRC uses to handle
warnings on a per request basis.
We entertained the idea of allowing you to set the warnings behavior to
strict mode on a per request basis but that wouldn't allow the high
level rest client to fail when it sees an unexpected warning.
We also entertained the idea of adding a list of "required warnings" to
the `RequestOptions` but that won't work well with failures that occur
*sometimes* like those we see in mixed clusters.
Adding a list of "allowed warnings" to the `RequestOptions` would work
for mixed clusters but it'd leave many of the assertions in our tests
weaker than we'd like.
This behavior plugging implementation allows us to make a "required
warnings" option when we need it and an "allowed warnings" behavior when
we need it.
I don't think this behavior is going to be commonly used by used outside
of the Elasticsearch build, but I expect they'll be a few commendably
paranoid folks who could use this behavior.
Moves all remaining (rolling-upgrade and mixed-version) REST tests to use Zen2. To avoid adding
extra configuration, it relies on Zen2 being set as the default discovery type. This required a few
smaller changes in other tests. I've removed AzureMinimumMasterNodesTests which tests Zen1
functionality and dates from a time where host providers were not configurable and each cloud
plugin had its own discovery.type, subclassing the ZenDiscovery class. I've also adapted a few tests
which were unnecessarily adding addTestZenDiscovery = false for the same legacy reasons. Finally,
this also moves the unconfigured-node-name REST test to Zen2, testing the auto-bootstrapping
functionality in development mode when no discovery configuration is provided.
