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.

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.

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.
This commit adds a test that checks that we are closing
all files even if there are random IOExceptions happening. The test
found several places where due to IOExceptions streams were not
closed due to unsufficient exception handling.
MockDirectoryWrapper adds asserting logic to the low level directory
implementation that helps to track and catch resource leaks like
unclosed index inputs caused by dangling IndexReader or IndexSearcher
instances. It prevents double writes to files and allows low level
random exceptions to be thrown for testing index consistency etc.
Closes#3654
Tests now support ignoring integartion tests by passing
'-Dtests.integration=false' to the test runner either via IDE or
maven to only run fast unittests.
Dynamic mapping allow to dynamically introduce new fields into an existing mapping. There is a (pretty rare) race condition, where a new field/object being introduced will not be immediately visible for another document that introduces it at the same time.
closes#3667, closes#3544
Improved LoggingListener (which reads and applies @TestLogging annotation) to take into account the logger prefix. We can now use the @TestLogging annotation and specify either the whole package name (e.g. o.e.action.metadata) or only the package name without the logger prefix (action.metadata), the custom log level will be properly applied in both cases
Enabled trace logging for RecoveryPercolatorTests#testMultiPercolator_recovery test
Cleaned up and removed unnecessary usage of concurrent collections.
The clear scroll api allows clear all resources associated with a `scroll_id` by deleting the `scroll_id` and its associated SearchContext.
Closes#3657
Now with have proper exit codes for elasticsearch plugin manager (see #3463), we can add a silent mode to plugin manager.
```sh
bin/plugin --install karmi/elasticsearch-paramedic --silent
```
Closes#3628.
