This commit replaces instances of manually computing a hash code for
primitive longs by XORing the upper bits with the lower bits with a
built-in method for doing the same.
This adds an API for force merging lucene segments. The `/_optimize` API is now
deprecated and replaced by the `/_forcemerge` API, which has all the same flags
and action, just a different name.
This commit removes some cache concurrency level settings that were
applicable when the cache was backed by the Guava cache implementation,
but no longer apply with the cache implementation completed in #13717.

Rest tests are now part of the verify goal, thus if we only want to execute those we need to skip unit tests, otherwise we'll get an error saying that the test phase completed without running any tests.
Today we leak the notion of an engine outside of the shard abstraction
which is not desirable. This commit refactors the infrastrucutre to use
use already existing interfaces to communicate if a shard has failed and
prevents engine private classes to be implemented on a higher level.
This change is purely cosmentical...
This commit removes some build output files from the
burn_maven_with_fire_branch that appear to have been mistakenly
committed to master in bfb9054a11.
This is very simple to do and recommended by `privileges(5)` documentation:
```
Daemons that never need to exec subprocesses should remove the PRIV_PROC_EXEC privilege from their permitted and limit sets.
```
Closes#14200
Adds *Exception(Throwable cause) constructors and calls them where appropriate
thus getting rid of 16 instances of calling getMessage and eliminating the risk
of loosing exception context.
Fixes ElasticsearchTimeoutException along the way (used to discard the
parameter args in the (String message, Object... args) constructor, passes it
up to super now.

Geopoint's equals method was modified to consider two points equal if they are within a threshold. This change was done to accept round-off error introduced from GeoHash encoding methods. This commit removes this trappy leniency from the GeoPoint equals method and instead forces round-off error to be handled at the encoding source.
This commit renames ShardReplicationTests to
TransportReplicationActionTests. This rename is to reflect the fact
that the tests contained in this test suite are for testing
TransportReplicationAction. This class was previously renamed but the
test suite was not.
Does so by improving the error message passed to MapperParsingException.
The error messages for mapping conflicts now look like:
```
{
"error" : {
"root_cause" : [ {
"type" : "mapper_parsing_exception",
"reason" : "Failed to parse mapping [type_one]: Mapper for [text] conflicts with existing mapping in other types:\n[mapper [text] has different [analyzer], mapper [text] is used by multiple types. Set update_all_types to true to update [search_analyzer] across all types., mapper [text] is used by multiple types. Set update_all_types to true to update [search_quote_analyzer] across all types.]"
} ],
"type" : "mapper_parsing_exception",
"reason" : "Failed to parse mapping [type_one]: Mapper for [text] conflicts with existing mapping in other types:\n[mapper [text] has different [analyzer], mapper [text] is used by multiple types.

Closes#12839
Change implementation
Rather than make a new exception this improves the error message of the old
exception.
we are relying on terminate_after more and more, replaced the limit filter with it and soon it will also replace the search_exists api. At that point we should make it a stable api rather than experimental.
Closes#14183
MetaDataSerivce tried to protect concurrent index creation/deletion
from resulting in inconsistent indices. This was originally added a
long time ago via #1296 which seems to be caused by several problems
that we fixed already in 2.0 or even in late 1.x version. Indices where
recreated without being deleted and shards where deleted while being used
which is now prevented on several levels. We can safely remove the semaphores
since we are already serializing the events on the cluster state threads.
This commit also fixes some expception handling bugs exposed by the added test
We currently have two, which is confusing when you read the code (especially if one is used with a null default and the other with '*')
Note: this is not a real bug, just a clean up. We do the right thing...
Closes#13988
After a full cluster restart, the elected master is tasked with recovery the last known cluster state from disk. To do so, the GatewayService registers it self as a listener to cluster state changes, triggering the recovery if the local node is elected. Sadly the initial post-election cluster state can be missed if it's being processed while the listener is registered (i.e., the listener is too late but the discoveryService.initialStateReceived is not yet set). In this case the cluster state from disk will be recovered with the next change (typically node join).
In practice this is not a big deal as master election takes at least 3s (by which time the gateway is long started), but it does make some of our tests to fail: http://build-us-00.elastic.co/job/es_core_master_centos/7915/
To fix this, we submit a cluster state task after the edition of the listener, so we are guaranteed to check things while they are at rest.
While at it, I removed some left over latch which we don't really wait on anymore.
Closes#13997
When we check the engine if a flush is needed we don't catch EngineClosedException today
but the engine is potentially closed already in which case we can simply return false and don't need
to bubble up the exception.
This commit fixes an issue where when starting Elasticsearch in
daemonized mode, a failed startup would not cause a non-zero exit code
to be returned. This can prevent the SysV init system from detecting
startup failures.
Closes#14163
Closed indices are currently out of scope for snapshots and shard migration,
and can cause issues in managed environments – where closing an index does
not necessarily make sense, as it still consumes the managed environment's storage quota.
This commit adds an option to dynamically disable closing indices via node or cluster settings.
Closes#14168
We used to change the minimumShouldMatch field of the query depending on the context, the final minimim should match should still be applied based on that, but the original minimumShouldMatch of the query shouldn't change. This was revelead by some recent test failure.
Closes#14153
