Compared to setting node.local to true, would be nicer to support node.mode with values of local or network.
Note, node.local is still supported.

The SearchWithRandomExceptionTests aim to catch problems when resources
are not closed due to exceptions etc. Yet in some cases the random seeds
cause the index to never be fully allocated so we basically go into a
ping-pong state where we try to allocate shards back and forth on nodes.
This causes all docs to time out which in-turn causes the tests to run
for a very long time (hours or days).
If we can not allocate the index and get to a yellow state we simply
index only one doc and expected all searches to fail.
This commit also beefs up the assertions in this test to check if
documents are actually present if they are indexed and refresh was
successful.
Closes#3694
Stats can be retrieved on a per-feature / per-component basis including the fields
they apply to. This commit add support for a 'completion' flag to include statistics
for the complition feature as well as 'completion_fields' to only
include certain fields into the returned statistics.
To disambiguate between 'fielddata' and 'completion' fields this commit
uses 'fields' as the default inclusion filter for stats fields only used
if not dedicated '[completion|fielddata]_fields' paramter is provided.
Relates to #3522
Add a dedicated suggest thread pool for the suggest API. With the new completion suggest type, which is purely CPU bounded, it makes more sense to have a dedicated thread pool for suggest compared to having it share the search thread pool and "competing" against other search operations.
closes#3698
When a dynamic type is introduced during indexing, the node that introduces it sends the fact that its added to the master, to be added to the master node. The master node then adds it to the index metadata and republishes that fact.
In order not to delete the mapping while the new type is introduced on the node that introduced it, we keep a map of seen mappings, and remove a mapping type when we already processed it.
The map is not properly cleared though in all places where an actual index service is being removed on a node.
closes#3697
Refresh flag in optimize is problematic, since the shards refresh is allowed to execute on is different compared to the optimize shards. In order to do optimize and then refresh, they should be executed as separate APIs when needed.
closes#3690
Refresh flag in flush is problematic, since the shards refresh is allowed to execute on is different compared to the flush shards. In order to do flush and then refresh, they should be executed as separate APIs when needed.
closes#3689
Both package types, RPM and deb now contain an option to not restart on upgrade.
This option can be configure in /etc/default/elasticsearch for dpkg based systems
and /etc/sysconfig/elasticsearch for rpm based systems.
By default the setting is as before, where a restart is executed on upgrade.
Closes#3685
In case of retries, we update the clusterState and shardsIt, make sure they are visible using volatile (even though updates will probably go through a memory barrier, this might explain rare failure we see when retry happens)
Introduced ElasticsearchAssertions that check for failures in all response
Added comment to flush requests as we don't check for failures there
Attempt to remove Thread.sleep in testChangeInitialShardsRecovery in favour of awaitBusy block
Added awaitBusy block in testQuorumRecovery waiting for YELLOW. We could have GREEN after the close node but wa want to wait for the YELLOW state.
As we are within an awaitBusy block, it doesn't make sense to have an assertion, since it would fail the test instead of waiting till the condition is verified (till timeout expires)
In 0.90.4, we deprecated some code:
* `GetIndexTemplatesRequest#GetIndexTemplatesRequest(String)` moved to `GetIndexTemplatesRequest#GetIndexTemplatesRequest(String...)`
* `GetIndexTemplatesRequest#name(String)` moved to `GetIndexTemplatesRequest#names(String...)`
* `GetIndexTemplatesRequest#name()` moved to `GetIndexTemplatesRequest#names()`
* `GetIndexTemplatesRequestBuilder#GetIndexTemplatesRequestBuilder(IndicesAdminClient, String)` moved to `GetIndexTemplatesRequestBuilder#GetIndexTemplatesRequestBuilder(IndicesAdminClient, String...)`
* `IndicesAdminClient#prepareGetTemplates(String)` moved to `IndicesAdminClient#prepareGetTemplates(String...)`
* `AbstractIndicesAdminClient#prepareGetTemplates(String)` moved to `AbstractIndicesAdminClient#prepareGetTemplates(String...)`
We can now remove that old methods in 1.0.
**Note**: it breaks the Java API
Relative to #2532.
Closes#3681.
/_template shows: No handler found for uri [/_template] and method [GET]
It would make sense to list the templates as they are listed in the /_cluster/state call.
Closes#2532.
