In order to get a quick overview using by simply checking the cluster state
and its corresponding cat API, the following two attributes have been added
to the cluster health response:
* task max waiting time, the time value of the first task of the
queue and how long it has been waiting
* active shards percent: The percentage of the number of shards that are in
initializing state
This makes the cluster health API handy to check, when a fully restarted
cluster is back up and running.
Closes#10805
The change makes rest-spec-api a project in the same way as we build dev-tools. it packages the tests and api in a bundle using the maven-remote-resources-plugin and uses the same plugin in the plugins and core pom to unpack the rest-api-spec into the target directory and references the rest tests there in the test resources.
The main stimulus for this change is that for those using Eclipse the current build does not work. After running `mvn eclipse:eclipse` the Eclipse IDE errors because the rest-api-spec is outside of the project scope, meaning that every time the command is run (required whenever any dependencies change), the class path of all the projects has to be manually fixed.
This fixes an issue to allow for negative unix timestamps.
An own printer for epochs instead of just having a parser has been added.
Added docs that only 10/13 length unix timestamps are supported
Added docs in upgrade documentation
Fixes#11478
Tests relying on sleeps and latch timeouts are prone to weird timing issues
and hard to read / understand error messages. This commit moves towards a more
deterministic error model and replaces empty fails with real exceptions.
Some repository verification exceptions are currently only returned to the users but not logged on the nodes where the exceptions occurred, which makes troubleshooting difficult.
Closes#11760
For #8871, we need to be able to check field types are compatible,
without comparing FieldMappers. This change moves the simulation
checks (which generate merge conflicts) for any properties of
MappedFieldTypes into a new method, validateCompatible.
This also simplifies the merge code which merges settings
between the old and new fieldtypes. Previously, each subclass
of FieldMapper would have to set its own fieldtype settings.
However, now that we have .clone(), which perfectly copies
all properties (with subclasses accounted for), we can now
do a simple clone when merging.
Finally, this fixes a subtle bug in merging, in which if
merging has conflicts, and we were not simulating, we would
still update the field type, even though it was not compatible!
NOTE: there is one test failure I am trying to track down with
timestamp merging. Otherwise, all tests pass.
Currently, we delete the shard _state file on engine failure.
This behaviour does not persist the engine failure reason for later inspection.
This commit marks the shard store as corrupted instead of deleting
the _state file to ensure the store index can not be opened after and
the engine failure is persisted.
CommonTermsQueryParser does not check for disable_coords, only for
disable_coord. Yet the builder only outputs disable_coords, leading to
disabling the coordination factor to be ignored in the Java API.

Replace the previous example which leveraged a range filter, which causes unnecessary confusion about when to use a range filter to create a single bucket or a range aggregation with exactly one member in ranges.
Closes#11704
I was unable to get my BulkProcessor script to work without importing the "ByteSizeUnit" and "ByteSizeValue" classes. Perhaps I overlooked something in the example and do not understand its code.
Need to reset the registered setting in order to make sure the nex round will capture the right delay interval
also randomize setting and name the setting properly
closes#11759
Added several classes to support expressions being used for numerical
calculations in aggregations. Expressions will still not compile
when used with mapping and update script contexts.
Closes#11596Closes#11689
With a recent change in core, we don't support anymore non explicit byte size units when setting values.
This commit fix that in azure repository. Otherwise, tests can't be executed.
Allow to set delayed allocation timeout on unassigned shards when a node leaves the cluster. This allows to wait for the node to come back for a specific period in order to try and assign the shards back to it to reduce shards movements and unnecessary relocations.
The setting is an index level setting under `index.unassigned.node_left.delayed_timeout` and defaults to 0 (== no delayed allocation). We might want to change the default, but lets do it in a different change to come up with the best value for it. The setting can be updated dynamically.
When shards are delayed, a log message with "info" level will notify how many shards are being delayed.
An implementation note, we really only need to care about delaying allocation on unassigned replica shards. If the primary shard is unassigned, anyhow we are going to wait for a copy of it, so really the only case to delay allocation is for replicas.
