You can use `_reindex` and `random_score` to extract a random
subset of an index but you have to be careful to sort by `_score`
or it won't work.

When logging a mock exception, Log4j attempts to render the stack
trace. On a mock exception, this will be null and Log4j will hit a
NullPointerException. This NullPointerException will get recorded in the
status logger buffer that we use to ensure that we do not having any
misuses of Log4j in production code. This commit replaces the use of a
mock exception with an actual exception to avoid angering the Log4j
assertions in ESTestCase.
Today when a message is not fully read on a response, we log (among
other details) the handler name. Unfortunately, if the handler is a
wrapper, all that we see is
o.e.t.TransportService$ContextRestoreResponseHandler@7446ba18
completely losing the offending handler. This commit adds an override
for TransportService$ContextRestoreResponseHandler#toString so that the
underlying offender can be discovered.

Today when handling responses from nodes in TransportNodesAction, if a
node timeouts or some other failure occurs and the action is not
accumulating exceptions, we log a confusing message:
org.elasticsearch.action.admin.cluster.stats.TransportClusterStatsAction]
ignoring unexpected response [null] of type [null], expected
[ClusterStatsNodeResponse] or [FailedNodeException]
Moreover, the original exception is completely lost. Since this log
message is confusing and unhelpful, we can drop it. Instead, we hold
onto the exception and log it at the warn level before dropping it from
the response.

This commit updates JodaTime to version 2.9.5 that contain a fix for a bug when parsing time zones (see https://github.com/JodaOrg/joda-time/pull/332, https://github.com/JodaOrg/joda-time/issues/386 and https://github.com/JodaOrg/joda-time/issues/373).
It also remove the joda-convert dependency that seems to be unused.
closes#20911
Here is the changelog for 2.9.5:
```
Changes in 2.9.5
----------------
- Add Norwegian period translations [#378]
- Add Duration.dividedBy(long,RoundingMode) [#69, #379]
- DateTimeZone data updated to version 2016i
- Fixed bug where clock read twice when comparing two nulls in DateTimeComparator [#404]
- Fixed minor issues with historic time-zone data [#373]
- Fix bug in time-zone binary search [#332, #386]
The fix in v2.9.2 caused problems when the time-zone being parsed
was not the last element in the input string. New approach uses a
different approach to the problem.
- Update tests for JDK 9 [#394]
- Close buffered reader correctly in zone info compiler [#396]
- Handle locale correctly zone info compiler [#397]
```
Given that the default is now 1, the comment in the config file was outdated. Also considering that the default value is production ready, we shouldn't list it among the values that need attention when going to production.

In the test for reindex and friend's rethrottling feature we were waiting
only for a single reindex sub task to start before rethrottling. This
mostly worked because starting tasks is fast. But it didn't *always work
and CI found that for us. This fixes the test to wait for all subtasks
to start before rethrottling.
I reproduced this locally semi-consistently with some fairly creative
`Thread.sleep` calls and this test fix fixes the issue even with the
sleeps so I'm fairly sure this will work consistently.
Closes#21446
The method used to be called `isSourceEmpty`, and was renamed to `hasSource`, but the return value never changed. Updated tests and users accordingly.
Closes#21419
This commit ensure that VirtualBox is available in version 5.1+ in the system before running packaging tests. It also check for Vagrant version is now greater than 1.8.6.
The environment variable ES_JVM_OPTIONS allows end-users to specify a
custom location for the jvm.options file. Unfortunately, this
environment variable is not exported from the SysV init scripts. This
commit addresses this issue, and includes a test that ES_JVM_OPTIONS and
ES_JAVA_OPTS work for the SysV init packages.

This changes these messages to be logged at the DEBUG level, so they
will not show up by default.
Currently, `executeIndexRequestOnPrimary` and `executeDeleteRequestOnPrimary`
methods used to prepare and execute write operations, modifies the provided
request, updating the version and versionType. This commit makes it the
callers responsibility to update request version and versionType and avoids
mutating the provided request in the execute methods.
This commit introduces a new execution mode for the
`simple_query_string` query, which is intended down the road to be a
replacement for the current _all field.
It now does auto-field-expansion and auto-leniency when the following criteria
are ALL met:
The _all field is disabled
No default_field has been set in the index settings
No fields are specified in the request
Additionally, a user can force the "all-like" execution by setting the
all_fields parameter to true.
When executing in all field mode, the `simple_query_string` query will
look at all the fields in the mapping that are not metafields and can be
searched, and automatically expand the list of fields that are going to
be queried.
Relates to #20925, which is the `query_string` version of this work.
This is basically the same behavior, but for the `simple_query_string`
query.

This commit clarifies some log messages for the bootstrap checks. The
message is that the user has limits set that are below the minimums that
Elasticsearch requires.

Null safe dereferences make handling null or missing values shorter.
Compare without:
```
if (ctx._source.missing != null && ctx._source.missing.foo != null) {
ctx._source.foo_length = ctx.source.missing.foo.length()
}
```
To with:
```
Integer length = ctx._source.missing?.foo?.length();
if (length != null) {
ctx._source.foo_length = length
}
```
Combining this with the as of yet unimplemented elvis operator allows
for very concise defaults for nulls:
```
ctx._source.foo_length = ctx._source.missing?.foo?.length() ?: 0;
```
Since you have to start somewhere, we started with null safe dereferenes.
Anyway, this is a feature borrowed from groovy. Groovy allows writing to
null values like:
```
def v = null
v?.field = 'cat'
```
And the writes are simply ignored. Painless doesn't support this at this
point because it'd be complex to implement and maybe not all that useful.
There is no runtime cost for this feature if it is not used. When it is
used we implement it fairly efficiently, adding a jump rather than a
temporary variable.
This should also work fairly well with doc values.
This commit removes some references to 5.x that were picked up when the
migration docs for the cat API were migrated from 5.x to master.

This commit adds migration docs for the cat API, including a note
regarding the change in response in the cat thread pool API for
unbounded queue sizes.

This commit ensures that we always restore the thread's original context after execution of
a context preserving runnable. We always wrap runnables in a wrapper that restores the context
at the time it was submitted to the execute method. The ContextPreservingAbstractRunnable
would restore the calling context in the doRun method and then in a try with resources
block would restore the thread's original context. However, the onFailure and onAfter methods
of a AbstractRunnable could modify the thread context and this modified thread context would
continue on as the thread's context after it was returned to the pool and potentially used
for a different purpose.
This change simply makes the level of the ant timestamp for waiting on
the integ test cluster echo at the info level instead of warn (the
default) so that it is only output when running with gradle --info, or
when the wait condition fails.
* Plugins: Convert custom discovery to pull based plugin
This change primarily moves registering custom Discovery implementations
to the pull based DiscoveryPlugin interface. It also keeps the cloud
based discovery plugins re-registering ZenDiscovery under their own name
in order to maintain backwards compatibility. However,
discovery.zen.hosts_provider is changed here to no longer fallback to
discovery.type. Instead, each plugin which previously relied on the
value of discovery.type now sets the hosts_provider to itself if
discovery.type is set to itself, along with a deprecation warning.
If you try to reindex with multiple slices against a node that
doesn't support it we throw an `IllegalArgumentException` so
`assertVersionSerializable` is ok with it and so if this happens
in REST it comes back as a 400 error.
* Rest client: don't reuse that same HttpAsyncResponseConsumer across multiple retries
Turns out that AbstractAsyncResponseConsumer from apache async http client is stateful and cannot be reused across multiple requests. The failover mechanism was mistakenly reusing that same instance, which can be provided by users, across retries in case nodes are down or return 5xx errors. The downside is that we have to change the signature of two public methods, as HttpAsyncResponseConsumer cannot be provided directly anymore, rather its factory needs to be provided which is going to be used to create one instance of the consumer per request attempt.
Up until now we tested our RestClient against multiple nodes only in a mock environment, where we don't really send http requests. In that scenario we can verify that retries etc. work properly but the interaction with the http client library in a real scenario is different and can catch other problems. With this commit we also add an integration test that sends requests to multiple hosts, and some of them may also get stopped meanwhile. The specific test for pathPrefix was also removed as pathPrefix is now randomly applied by default, hence implicitly tested. Moved also a small test method that checked the validity of the path argument to the unit test RestClientSingleHostTests.
Also increase default buffer limit to 100MB and make it required in default consumer
The default buffer limit used to be 10MB but that proved not to be high enough for scroll requests (see reindex from remote). With this commit we increase the limit to 100MB and make it a bit more visibile in the consumer factory.
This commit cleans up the formatting of some Javadocs in
BootstrapCheck.java, and corrects some docs that had become stale as the
bootstrap checks evolved.
