We now return acknowledged true when no wait is needed (mustAck always returns false). We do wait for the master node to complete its actions though. Previously it would try to timeout and hang due to a CountDown#fastForward call when the internal counter is set to 0
We now return acknowledged false without starting the timeout thread when the timeout is set 0, as starting the wait and immediately stopping the thread seems pointless.
Added coverage for ack in ClusterServiceTests
this map is a "true" immutable map, encapsulating an open impl, and has a builder that allows it to be built easily.
the builder has the optimization of using clone if its being built based on an existing immutable map.
Usually acknowledged true means that all nodes have digested the change and are in sync. When no changes are made, there is no need to push a new cluster state, no need to wait for ack either, but can't guarantee that all nodes are in sync.
When using cluster reroute with dryRun flag no changes are made, this test was based on the wrong assumption that acknowledged meant all nodes were in sync, which is not the case here.
Changed the test to only read the cluster state from the master, to check that nothing changed there after processing the cluster state update.
we need to move to started from post recovery on cluster level changes, we need to make sure we handle a global state change of relocating, which can happen (and not pass through started)
Improve the introduction of new fields into the concrete parsed mappings by not relying on immutable maps and copying over entries, but instead using open maps (which will also use less memory), and using clone to perform the copy on write logic
This allows the RegexpQueryBuilder to be used in span queries
Added tests for all span multi term queries.
Also updated the documentation and removed mentioning of numeric range
queries for span queries (they have to be terms).
Closes#3392
This new API allows to get the mapping for a specific set of fields rather than get the whole index mapping and traverse it.
The fields to be retrieved can be specified by their full path, index name and field name and will be resolved in this order.
In case multiple field match, the first one will be returned.
Since we are now generating the output (rather then fall back to the stored mapping), you can specify `include_defaults`=true on the request to have default values returned.
Closes#3941
its preferable to execute the indices cluster state service as quickly as possible, as one of the first listeners, so it will apply the cluster state to the local state
potentially, it should even execute before it state is "visible" (through the state call), but that's another change...
make sure to throw the already exists exception, so when indexing into an alias, and it has not propagated yet through the cluster state, it will end up being ignored if it already exists
Some FieldData consumers require hash values per byte. We provide an optimization
that allows to cache the hashes internally if the consumer knows that they are needed
this optimization got lost in a previous commit. This commit adds them back and folds
the dedicated method into AtomicFieldData#getBytesValues(true|false)
As a side note, the internal reroute call is now part of the ack mechanism. That means that if the response contains acknowledged flag, the internal reroute that was eventually issued was acknowledged too. Also, even if the request is not acknowledged, the reroute is issued before returning, which means that there is no need to manually call reroute afterwards to make sure the new settings are immediately applied.
Closes#3995
Added support for serialization based on version to AcknowledgedResponse. Useful in api that don't support yet the acknowledged flag in the response.
Moved also ack warmer tests to more specific AckTests class
Close#3983
This addes the _cat/recovery/{index} API endpoint, which displays
information about the status of recovering shards. An example of the
output:
