Currently we throw misleading exception in acquireSearcher
if we try to acquire while we are failing the engine. We should
throw an EngineClosedException instead.
Relates to #5633
When refresh failed, it would fail due to a serious issue in the shard (mainly corrupted index). Fail the engine in that cause, which will cause the shard to fail. The reason why its not only on CorruptedIndex failed is that any type of failure seems to be relevant here to fail the shard

Update RelocationTests to use the above and unified testPrimaryRelocationWhileIndexing & testReplicaRelocationWhileIndexingRandom into a single randomized test.
This commit speeds up aggregations tests dramatically since they all
rely on the same index structure. Here we can safe a large amout of time
to not recreate the index for each small test.
All the ordinary test operations happen based on the ImmutableTestCluster base class and are executed via transport client. Will be used especially for the REST tests once migrated to the standard randomized runner.
Added new httpAddresses method to ImmutableTestCluster to be able to retrieve the http addresses to connect to for the REST tests. Both versions will look inside the cluster to figure out which nodes are available for http calls and their addresses.
The external cluster is used as global cluster if the tests.cluster system property is available. The property needs to contain a comma separated list of available elasticsearch nodes that will be used to connect to the cluster (e.g. localhost:9300,localhost:9301).
Only a subset of the integration tests can currently be run successfully against the external cluster, for more precision the ones that don't modify the cluster layout (don't require cluster() functionalities but rely only on immutableCluster()). Also at least two data nodes are required otherwise the ensureGreen calls cannot succeed.
Closes#5630
The way that SearchServiceTransportAction executes actions on a local node
today would propagate exceptions thrown in onResult to onFailure.

An infrastructure that allows to simulate different network topologies failures, including 2 basic ones in failure to send requests, and unresponsive nodes
closes#5631
Today the clusterstate is not asssociated with the cluster_name which is odd
since it's pretty much it's only valid identifier. Any node can send a cluster
state to another node today even if it's not the same cluster. These situations
can happen rarely during tests or even in the wild by accident.
- removed an abstraction layer that handles the values source (consolidated values source with field data source)
- better handling of value parser/formatter in range & histogram aggs
- the buckets key will now be shown by default in range agg
simplify rest response class hierarchy, by using BytesReference for content, and handling JSONP internally in the respective channel that sends the response.
Also, handle the future case where bytes might be releasable, when we start to potentially recycle bytes output stream.
A bunch of minor fixes have been included here, especially due
to wrongly parsed mappings. Also using assertions resulted in an
NPE because they were disabled in the distribution.
Closes#5525
The new base class contains all the immutable methods for a cluster, which will be extended by the future ExternalCluster impl that relies on an external cluster and won't be adding nodes etc. but only sending requests to an existing cluster whose layout never changes
Closes#5620
Before a bulk request is executed, missing indices are being created by default.
If this fails, the whole request is failed.
This patch changes the behaviour to not fail the whole request, but rather all
requests using the index where the creation has failed.
Closes#4987
If a node fails to forward a master node operation to the current master, it will schedule a retry using a listener for cluster state changes. Once the listener is in place (and future changes are guaranteed to be observed) it will double check nothing has change during the addition of the listener. This check has previously been change to use cluster state versions (see: #5499). This is however not reliable solution as master elections (which change the master) do not increment the cluster state version and thus could be missed. This commit changes the check to use reference equality making it stricter.
Closes#5548
Although high-severity bugs were mostly static variables that were not final,
it also found potential NPEs and bugs like `x ^= x;` or equality checks on
objects that don't share a common interface.
