This commit reduces classes to handle write
operation results in TransportWriteAction, this
comes at the cost of handling write operations in
TransportShardBulkAction.
Now parsing, mapping failures (which happen before
executing engine write operation) are communicated
via a failure operation type while transient operation
failures are set on the index/delete operations.
This experimental setting enables relocation of shards that are being snapshotted, which can cause the shard allocation failures. This setting is undocumented and there is no good reason to set it in production.
This commit upgrades the transport-netty4 module dependency from Netty
version 4.1.5 to version 4.1.6. This is a bug fix release of Netty.

This commit cleans up the code handling load averages in OsProbe:
- remove support for BSD; we do not support this OS
- add Javadocs
- strengthen assertions and testing
- add debug logging for exceptional situation
Relates #21037
Follow up for #21039.
We can revert the previous change and do that a bit smarter than it was.
Patch tested successfully manually on ec2 with 2 nodes with a configuration like:
```yml
discovery.type: ec2
network.host: ["_local_", "_site_", "_ec2_"]
cloud.aws.region: us-west-2
```

Backport of #21048 in master branch
This change moves providing UnicastHostsProvider for zen discovery to be
pull based, adding a getter in DiscoveryPlugin. A new setting is added,
discovery.zen.hosts_provider, to separate the discovery type from the
hosts provider for zen when it is selected. Unfortunately existing
plugins added ZenDiscovery with their own name in order to just provide
a hosts provider, so there are already many users setting the hosts
provider through discovery.type. This change also includes backcompat,
falling back to discovery.type when discovery.zen.hosts_provider is not
set.
Here is what is happening without this fix when you try to connect to ec2 APIs:

For whatever reason, it can not parse what is coming back from http://169.254.169.254/latest/meta-data/iam/security-credentials/discovery-tests.
But, if you wrap the code within an `AccessController.doPrivileged()` call, then it works perfectly.
Closes#21039.
(cherry picked from commit abfdc70)
The max score returned in the response of a query does not take rescorer into account.
This change updates the max_score when a rescorer is used in a query.
Fixes#20651
This change adds a TypesQuery that checks if the disjunction of types should be rewritten to a MatchAllDocs query. The check is done only if the number of terms is below a threshold (16 by default and configurable via max_boolean_clause).
* Move all zen discovery classes into o.e.discovery.zen
This collapses sub packages of zen into zen. These all had just a couple
classes each, and there is really no reason to have the subpackages.
* fix checkstyle
Date math index/alias expressions in mget will now be resolved to a concrete single index instead of failing the mget item with an `IndexNotFoundException`.
Added also an integration test to verify multi index aliases do not fail the entire mget request.
Closes#17957
This commit removes an undocumented output parameter node_info_format
from the cluster stats and node stats APIs. Currently the parameter does
not even work as it is not whitelisted as an output parameter. Since
this parameter is not documented, we opt to just remove it.
Relates #21021
When indices stats are requested via the node stats API, there is a
level parameter to request stats at the index, node, or shards
level. This parameter was not whitelisted when URL parsing was made
strict. This commit whitelists this parameter.
Additionally, there was some leniency in the parsing of this parameter
that has been removed.
Relates #21024
This change makes the ElectMasterService local to ZenDiscovery, no
longer created by guice, and thus also removes the ability for plugins
to customize. This extension point is no longer used by anything.
This was an error-prone version type that allowed overriding previous
version semantics. It could cause primaries and replicas to be out of
sync however, so it has been removed.
This is related to #20377, which removed the feature entirely. This
allows operations to continue to use the `force` version type if the
index was created before 6.0, in the event a document using it exists in
a translog being replayed.
Previous to this change any request using a script sort in a top_hits
aggregation would fail because the compilation of the script happened
after the QueryShardContext was frozen (after we had worked out if the
request is cachable).
This change moves the calling of build() on the SortBuilder to the
TopHitsAggregationBuilder which means that the script in the script_sort
will be compiled before we decide whether to cache the request and freeze
the context.
Closes#21022
This commit removes an undocumented output parameter output_uuid from
the cluster stats API. Currently the parameter does not even work as it
is not whitelisted as an output parameter. Since the cluster UUID is
available from the main action, and this parameter is not documented, we
opt to just remove it.
Relates #21020
This allows you to whitelist `localhost:*` or `127.0.10.*:9200`.
It explicitly checks for patterns like `*` in the whitelist and
refuses to start if the whitelist would match everything. Beyond
that the user is on their own designing a secure whitelist.
