Add yet another warning about data loss to the introductory paragraph about the
unsafe commands. Also move this paragraph next to the details of the unsafe
commands, below the section on the `retry_failed` flag.
Be more specific about how to use the URI parameters and in-body flags.
Clarify statements about when rebalancing takes place (i.e. it respects
settings)
Resolves#16113.
Today when a resize operation is performed, we copy the analysis,
similarity, and sort settings from the source index. It is possible for
the resize request to include additional index settings including
analysis, similarity, and sort settings. We reject sort settings when
validating the request. However, we silently ignore analysis and
similarity settings on the request that are already set on the source
index. Since it is possible to change the analysis and similarity
settings on an existing index, this should be considered a bug and the
sort of leniency that we abhor. This commit addresses this bug by
allowing the request analysis/similarity settings to override the
existing analysis/similarity settings on the target.
Similarly to what has been done in for the repository-s3 plugin,
this commit moves the fixture test into a dedicated
repository-gcs/qa/google-cloud-storage project.
It also exposes some environment variables which allows to
execute the integration tests against the real Google Cloud
Storage service. When the environment variables are not
defined, the integration tests are executed using the fixture
added in #28788. Related to #29349.
The `testDeleteSnapshotWithMissingIndexAndShardMetadata` test uses an
obsolete repository directory structure based on index names instead of
UUIDs. Because it swallows exceptions when deleting test files the test
never failed when the directory structure changed.
This commit fixes the test to use the right directory structure and file
names and to not swallow exceptions anymore.
The REST resize handlers for shrink/split operations are effectively the
same code with a minor difference. This commit collapse these handlers
into a single base class.
This *mostly* silences `javadoc`'s warning about defaulting to
generating html4 files by enabling generating html5 file for the
projects for which that works. It didn't work in a half dozen projects,
about half of which I've fixed in this PR, entirely by replacing
`<tt>thing</tt>` with `{@code thing}`.
There are a few remaining projects that contain javadoc with invalid
html5. I'll fix those projects in a followup.
This is a code-tidying PR, a little side adventure while working on
another change. Previously only shrink request existed but when the
ability to split indices was added, shrink and split were done together
under a single request object: the resize request object. However, the
code inherited the legacy name in the naming of some variables. This
commit cleans this up.
A previous change modified the output of the thread pool info contained
in the nodes info API. This commit adds a note to the migration docs for
this change.
Since #28049, only fully initialized shards are received write requests.
This enhancement allows us to handle all exceptions. In #28571, we
started strictly handling shard-not-available exceptions and tried to
keep the way we report replication errors to users by only reporting if
the error is not shard-not-available exceptions. However, since then we
unintentionally always log warn for all exception. This change restores
to the previous behavior which logs warn only if an exception is not a
shard-not-available exception.

We *think* that #28600 is caused by warnings not being collected during
one of the fan out phases of search but we're not 100% sure how this is
happening. This commit drops the number of shards used for the test to 1
so there *isn't* a fan out phase. If this makes the issue go away we'll
have more information.
This folds the `:qa:reindex-from-old` project into the `:modules:reindex`
project. This should speed up the build marginally by removing a single
clsuter start up at the cost of having to wait for old versions of
Elasticsearch to start up when checking reindex's integration tests.
Those don't take that long so this feels worth it.
We had a number of awaitsFix links that weren't updated after the xpack
merge.
Where possible I changed the links to the new locations, but in some
circumstances the original ticket was closed (suggesting the awaitsfix
should be removed) or was otherwise unclear the status.
This commit moves the repository-s3 fixture test added in #29296 in a
new `repository-s3/qa/amazon-s3` project. This new project allows the
REST integration tests to be executed using the real S3 service when
all the required environment variables are provided. When no env var
is provided, then the tests are executed using the fixture added
in #29296.
The REST tests located at the `repository-s3`plugin project now only
verify that the plugin is correctly loaded.
The REST tests have been adapted to allow a bucket name and a base
path to be specified as env vars. This way it is possible to run the tests
with different base paths (could be anything, like a CI job name or a
branch name) without multiplicating buckets.

A NullPointerException is thrown when trying to create or delete
a snapshot in a repository that has been written to by an older
Elasticsearch after writing to it with a newer Elasticsearch version.
This is because the way snapshots are formatted in the repository
snapshots index file changed in #24477.
This commit changes the parsing of the repository index file so that
it now detects a corrupted index file and fails early the snapshot
operation.

We already had *some* documentation of the batch nature of `reindex` and
friends but it wasn't super obvious how it interacted with the
`failures` element in the response. This adds some more documentation
the `failures` element.
The global ordinals terms aggregator has an option to remap global ordinals to
dense ordinal that match the request. This mode is automatically picked when the terms
aggregator is a child of another bucket aggregator or when it needs to defer buckets to an
aggregation that is used in the ordering of the terms.
Though when building the final buckets, this aggregator loops over all possible global ordinals
rather than using the hash map that was built to remap the ordinals.
For fields with high cardinality this is highly inefficient and can lead to slow responses even
when the number of terms that match the query is low.
This change fixes this performance issue by using the hash table of matching ordinals to perform
the pruning of the final buckets for the terms and significant_terms aggregation.
I ran a simple benchmark with 1M documents containing 0 to 10 keywords randomly selected among 1M unique terms.
This field is used to perform a multi-level terms aggregation using rally to collect the response times.
The aggregation below is an example of a two-level terms aggregation that was used to perform the benchmark:
```
"aggregations":{
"1":{
"terms":{
"field":"keyword"
},
"aggregations":{
"2":{
"terms":{
"field":"keyword"
}
}
}
}
}
```
| Levels of aggregation | 50th percentile ms (master) | 50th percentile ms (patch) |
| --- | --- | --- |
| 2 | 640.41ms | 577.499ms |
| 3 | 2239.66ms | 600.154ms |
| 4 | 14141.2ms | 703.512ms |

Email message IDs are supposed to be unique. In order to guarantee this,
we need to take the action id of a watch action into account as well,
not just the watch id from the watch execution context. This prevents
that two actions from the same watch execution end up with the same
message id.
Clearing the cache indices can be done via GET and POST. As GET should
only support read only operations, this removes the support for using
GET for clearing the indices caches.
This is related to #30134. It modifies the start_trial action to require
an acknowledgement parameter in the rest request to actually start the
trial license. There are backwards compatibility issues as prior ES
versions did not support this parameter. To handle this, it is assumed
that a request coming from a node prior to 6.3 is acknowledged. And
attempts to write a non-acknowledged request to a prior to 6.3 node will
throw an exception.
Additionally this PR adds messages about the trial license the user is
generating.
This commit converts the deb package to use tildes in place of dash in
the internal package version. This is only relevant for prerelease
versions of elasticsearch. Previously, this was not possible due to
problems with the underlying library used by the ospackage plugin, but
since a recent upgrade, it now works.
closes#21139
Currently the test picks random java.util.TimeZone ids in some places.
Internally we still need to convert back to joda DateTimeZone by id
occassionally (e.g. when serializing to pre 6.3 versions). There are
some deprecated "SystemV/*" time zones that Jodas DateTimeZone refuses
to convert. This change excludes those rare cases from the set of
allowed random time zones. It would be quiet odd for them to appear in
practice.
Closes#30156
Adding some allowed abbreviated values for intervals in date histograms
as well as documenting the limitations of intervals larger than days.
Closes#23294
A few of the old style license got kept around because their comment
string did not start with a space. This caused the license check to not
see it as a license and skip it. This commit cleans it up.
This removes some monitoring tests that have been silenced for a long
time. These tests don't really provide any value for the upgrade suite and
they just create noise due to their occasional timing-related failures.
* add copyright/scope configuration for intellij
This commit introduces a section discussing the ability to define
copyright rules in intellij for inserting the appropriate copyright
headers into files across both apache2-Elasticsearch, as well as the
commercial code under `x-pack`.
Some other re-organization was made to create more sub-structure
* update to reflect reviewer comments
The purpose of this change is to reflect what is the future way of configuring aliases in
the Rollover action for ILM. With this change, users will be able to edit all desired rollover-related
information in the index's template, so that the index-lifecycle policy does not need to be dependent on it.
Add the oss tar distribution to the packaging test plugin. Test the oss
tar distribution in the core packaging tests, and the non-oss tar
distribution in the x-pack packaging tests.
Today we update index settings directly via IndexService instead of the
cluster state in IndexServiceTests. However, those changes will be lost
if there is a cluster state update. In general, we should update index
settings via client and limit the direct usage in only special tests.
This commit replaces direct usages by the updateSettings api of client.
