This commit simplifies the delayed shard allocation implementation by assigning clear responsibilities to the various components that are affected by delayed shard allocation:
- UnassignedInfo gets a boolean flag delayed which determines whether assignment of the shard should be delayed. The flag gets persisted in the cluster state and is thus available across nodes, i.e. each node knows whether a shard was delayed-unassigned in a specific cluster state. Before, nodes other than the current master were unaware of that information.
- This flag is initially set as true if the shard becomes unassigned due to a node leaving and the index setting index.unassigned.node_left.delayed_timeout being strictly positive. From then on, unassigned shards can only transition from delayed to non-delayed, never in the other direction.
- The reroute step is in charge of removing the delay marker (comparing timestamp when node left to current timestamp).
- A dedicated service DelayedAllocationService, reacting to cluster change events, has the responsibility to schedule reroutes to remove the delay marker.
Closes#18293
Failing the build on deprecation warnings was removed in
19b3ec88af. This commit removes the
suppressed deprecation warnings so that their use is surfaced in the
build now.

This adds modules.txt and plugins.txt to the core jar resource files,
which the install plugin command statically loads, in place of the
previously hardcoded lists (which have often gone out of date).
With the unified release, we will have staged releases based on a
unified hash (hash of all the hashes), so using the elasticsearch hash
for plugins staging will no longer work. This change makes the
`es.plugins.staging` property take the staging hash it should use.
- now you can specify a list of grok patterns to match your field with
and the first one to successfully match wins.
- only non-null captures will be inserted into your matched document.
Fixes#17903.
We have have a virtual build-tools project which pulls in all the same
IDE settings we have for other projects, so there is no longer a need
for hacking buildSrc into our IDEs.
We currently fail on any deprecations found during the build. However,
this includes things deprecated within ES, which adds a heavy burden in
order to deprecate apis (requring to add suppressions to all internal
callers of the API).
This change adds `-deprecation` to xlint. We should consider in the
future having a task to "see" what deprecated apis we currently use for
analysis.
`doc_values` for _type field are created but any attempt to load them throws an IAE.
This PR re-enables `doc_values` loading for _type, it also enables `fielddata` loading for indices created between 2.0 and 2.1 since doc_values were disabled during that period.
It also restores the old docs that gives example on how to sort or aggregate on _type field.
The setting minimum_master_nodes is crucial to avoid split brains in a cluster. In order to avoid data loss, it should always be configured to at least a quorum (majority) of master-eligible nodes.
This commit adds a warning to the logs on the master node if the value is set to less than quorum of master-eligible nodes.
The 'Setting' constructor has some outdated Javadoc that suggested that it would automatically apply 'Property.NodeScope' if no scope is supplied, but no scope is added in that case.
We still maintain BWC for the translog operations back to 1.1 which is not
supported in the current version anyway. This commit drops the bwc and moves
the operations to the Writeable interface enforcing immutability.
Closed indices are already displayed when no indices are explicitly selected. This commit ensures that closed indices are also shown when wildcard filtering is used. It also addresses another issue that is caused by the fact that the cat action is based internally on 3 different cluster states (one when we query the cluster state to get all indices, one when we query cluster health, and one when we query indices stats). We currently fail the cat request when the user specifies a concrete index as parameter that does not exist. The implementation works as intended in that regard. It checks this not only for the first cluster state request, but also the subsequent indices stats one. This means that if the index is deleted before the cat action has queried the indices stats, it rightfully fails. In case the user provides wildcards (or no parameter at all), however, we fail the indices stats as we pass the resolved concrete indices to the indices stats request and fail to distinguish whether these indices have been resolved by wildcards or explicitly requested by the user. This means that if an index has been deleted before the indices stats request gets to execute, we fail the overall cat request. The fix is to let the indices stats request do the resolving again and not pass the concrete indices.

SnapshotInfo had a toXContent and an externalToXContent, the former for
writing snapshot info to the snapshot blob and the latter for writing the
snapshot info to the APIs. This commit unifies writing x-content to one
method, toXContent, which distinguishes which format to write the
snapshot info in based on the Params parameter. In addition, it makes
use of the already existing snapshot specific params found in the
BlobStoreFormat.
Closes#18494
This change tweaks the metadata version associated with the deb and rpm
packages. For rpm, dashes are allowed in versions, so we can use the
version as it already exists. For rpm, dashes are not allowed, so this
uses underscores instead. This only affects prerelease versions (eg
alpha/beta/rc), and usually someone doesn't specify the version, so the
inconsistency doesn't matter that much.
This is a leftover spot that wasn't changed. It was breaking
ClusterSettingsIT#ClusterSettingsIT because that test expected
the test's log level to default to the default logger level for
the nodes.
The syntax highlighter only supports [source,js].
Also adds a check to the rest test generator that runs during
the build that'll fail the build if it sees `[source,json]`.
