The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
This commit adds deletion of the bin directory to postrm cleanup. While
the package's bin files are cleaned up by the package manager, plugins
may have created subdirectories under bin. We already cleanup plugins,
but not the extra bin dirs their installation created.

The deb package has been updated several times in the past to contain
overrides in order to pass lintian inspection. However, there have never
been any tests to ensure we do not fallback to failure. This commit
updates the overrides file given things that have changed since 2.x like
adding ML and bundling the jdk.

We have faked some Ivy repositories on a few artifact locations. Today
when Gradle attempts to resolve these artifacts, it follows its default
strategy to search for Gradle metadata, then Maven POM files, then Ivy
descriptors, and finally will fallback to looking directly for the
artifact. This wastes times on remote network calls that will 404 anyway
since these metadata resources will not exist for these fake Ivy
repositories. This commit overrides the Gradle strategy to look directly
for artifacts.
When Elasticsearch is run from a package installation, the running
process does not have permissions to write to the keystore. This is
because of the root:root ownership of /etc/elasticsearch. This is why we
create the keystore if it does not exist during package installation. If
the keystore needs to be upgraded, that is currently done by the running
Elasticsearch process. Yet, as just mentioned, the Elasticsearch process
would not have permissions to do that during runtime. Instead, this
needs to be done during package upgrade. This commit adds an upgrade
command to the keystore CLI for this purpose, and that is invoked during
package upgrade if the keystore already exists. This ensures that we are
always on the latest keystore format before the Elasticsearch process is
invoked, and therefore no upgrade would be needed then. While this bug
has always existed, we have not heard of reports of it in practice. Yet,
this bug becomes a lot more likely with a recent change to the format of
the keystore to remove the distinction between file and string entries.
hamcrest has some improvements in newer versions, like FileMatchers
that make assertions regarding file exists cleaner. This commit upgrades
to the latest version of hamcrest so we can start using new and improved
matchers.
The pid dir for both systemd and init.d is already managed by those
respective systems (tmpfiles.d and the init script, respectively). Since
the /var/run dir is often mounted as tmpfs, it does not make sense to
have the elasticsearch pid dir added by the package installation. This
commit removes that empty dir from deb and rpm.
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.

If the relocation is throttled, the subsequent search request on the

This commit deprecates versions of Java prior to Java 11. This commit
will cause a warning to be printed to standard error when any command

We recently introduced the option to minimize network roundtrips when

On windows, JAVA_HOME is currently resolved when the windows service is started. However, this is contrary to what our documentation states. This commit moves resolution to service install. This has the side effect of making java existence checking optional in elasticsearch-env.bat, since the rest of the service commands do not require java.

When a node is repurposed to master/no-data or no-master/no-data, v7.x
will not start (see #37748 and #37347). The `elasticsearch repurpose`
tool can fix this by cleaning up the problematic data.
This commit adds cd $ES_HOME to elasticsearch-env and removes it from
elasticsearch. This way, both elasticsearch and elasticsearch-cli are
executed with the working directory set to $ES_HOME. The need for the
fix arose from the following bug:
1. Explicitly set path.data to relative to ES_HOME path in
elasticsearch.yml.
2. Run elasticsearch from any directory. Elasticsearch is able to
correctly start.
3. Stop elasticsearch.
4. Run elasticsearch-node unsafe-bootstrap, not from ES_HOME directory.
It will fail with an exception.

This commit removes the cluster state size field from the cluster state
response, and drops the backwards compatibility layer added in 6.7.0 to
continue to support this field. As calculation of this field was
expensive and had dubious value, we have elected to remove this field.
This commit adds a variant for every official distribution that omits
the bundled jdk. The "no-jdk" naming is conveyed through the package
classifier, alongside the platform. Package tests are also added for
each new distribution.
Computing the compressed size of the cluster state on every invocation
of cluster:monitor/state action is expensive, and the value of this
field is dubious anyway. Therefore we want to remove computing this
field. As a first step, we stop computing and return this field by
default. To avoid breaking users, we will give them a system property to
use to tide them over until the next major release when we will actually
remove this field. This comes with a deprecation warning too, and the
backport to the appropriate minor will also include a note in the
migration guide. There will be a follow-up to remove this field in the
next major version.
Executors of type fixed_auto_queue_size (i.e. search / search_throttled) wrap runnables into
TimedRunnable, which is an AbstractRunnable. This is dangerous as it might silently swallow
exceptions, and possibly miss calling a response listener. While this has not triggered any failures in
the tests I have run so far, it might help uncover future problems.
Follow-up to #36137
* Bundle java in distributions
Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.
This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.

This back-ports how versions are determined and bwc test are set up from

Backport support for replicating closed indices (#39499)
Before this change, closed indexes were simply not replicated. It was therefore
possible to close an index and then decommission a data node without knowing
that this data node contained shards of the closed index, potentially leading to
data loss. Shards of closed indices were not completely taken into account when
balancing the shards within the cluster, or automatically replicated through shard
copies, and they were not easily movable from node A to node B using APIs like
Cluster Reroute without being fully reopened and closed again.
This commit changes the logic executed when closing an index, so that its shards
are not just removed and forgotten but are instead reinitialized and reallocated on
data nodes using an engine implementation which does not allow searching or
indexing, which has a low memory overhead (compared with searchable/indexable
opened shards) and which allows shards to be recovered from peer or promoted
as primaries when needed.
This new closing logic is built on top of the new Close Index API introduced in
6.7.0 (#37359). Some pre-closing sanity checks are executed on the shards before
closing them, and closing an index on a 8.0 cluster will reinitialize the index shards
and therefore impact the cluster health.
Some APIs have been adapted to make them work with closed indices:
- Cluster Health API
- Cluster Reroute API
- Cluster Allocation Explain API
- Recovery API
- Cat Indices
- Cat Shards
- Cat Health
- Cat Recovery

Finding java on the path is sometimes confusing for users and
unexpected, as well as leading to a different java being used than a
user expects. This commit adds warning messages when starting
elasticsearch (or any tools like the plugin cli) and using java found
on the PATH instead of via JAVA_HOME.
This test failed on 7.1 when running full cluster restart tests against pre-7.0
clusters (e.g. 6.6 clusters). The fixes the expected type in the
templates after the cluster restart.
Instead of using `WarningsHandler.PERMISSIVE`, we only match warnings
that are due to types removal.
This PR also renames `allowTypeRemovalWarnings` to `allowTypesRemovalWarnings`.

We have had various reports of problems caused by the maxRetryTimeout
setting in the low-level REST client. Such setting was initially added
in the attempts to not have requests go through retries if the request
already took longer than the provided timeout.
The implementation was problematic though as such timeout would also
expire in the first request attempt (see #31834), would leave the
request executing after expiration causing memory leaks (see #33342),
and would not take into account the http client internal queuing (see #25951).
Given all these issues, it seems that this custom timeout mechanism
gives little benefits while causing a lot of harm. We should rather rely
on connect and socket timeout exposed by the underlying http client
and accept that a request can overall take longer than the configured
timeout, which is the case even with a single retry anyways.
This commit removes the `maxRetryTimeout` setting and all of its usages.
Instead of logging warnings we now rethrow exceptions thrown inside
scheduled/submitted tasks. This will still log them as warnings in
production but has the added benefit that if they are thrown during
unit/integration test runs, the test will be flagged as an error.
This is a continuation of #38014
