If a folder for an index was created that folder is never deleted from that node unless the index is deleted.
Data only nodes therefore can have empty folders for indices that they do not even have shards for.
This commit makes sure empty folders are cleaned up after all shards have moved away from a data only
node. The behavior is unchanged for master eligible nodes.

The Histogram and Range APIs for the aggregations changed so that there was a common interface between he types of Range/Histogram. This PR reflects that change in the Java API docs

Delete-by-query is incredibly costly because it forces a refresh each
time, so if you are also indexing this can cause massive segment
explosion.
This change throttles delete-by-query when merges can't keep up. It's
likely not enough (#7052 is the long-term solution) but can only
help.
Closes#9986
In TransportSearchTypeAction one of the logger calls was passing the throwable in as a parameter for the message rather than a throwable to be printed as a stack trace. This change fixes it so the throwable is printed properly
We used to handle truncated translogs in a better manner (assuming that
the node was killed halfway through writing an operation and discarding
the last operation). This brings back that behavior by catching an
`EOFException` during the stream reading and throwing a
`TruncatedTranslogException` which can be safely ignored in
`IndexShardGateway`.
Fixes#9699
We've been relying on URI for url encoding, but it turns out it has some problems. For instance '+' stays as is while it should be encoded to `%2B`. If we go and manually encode query params we have to be careful though not to run into double encoding ('+'=>'%2B'=>'%252B'). The applied solution relies on URI encoding for the url path, but manual url encoding for the query parameters. We prevent URI from double encoding query params by using its single argument constructor that leaves everything as is.
We can also revert back the expression script REST test that revealed this to its original content (which contains an addition).

It may take some time for the old master node to step down anf for it to rejoin and that all nodes have it in the nodes list.
By waiting for the old master node to have stepped down, we can again rely on assertDiscoveryCompleted() to make sure that it has joined.
If the isolated unicast host is also a master node then its local cluster state gets unusable a source for pinging when the disruption stops.
All the nodes in the cluster state node list can be removed and at that time it will only ping itself and never find out about the other nodes.
(these nodes will not ping, because they are already following a new master)
CurrentTestFailedMarker is a RunListener that gets notified whenever a test fails, and we were using it to be able to restart the suite cluster after each failure. We were checking whether a test had failed in the @After method though, which runs before the listener gets notified, so the failed flag would always be false.
This commit makes sure that the suite cluster gets restarted not only when there are problems in the afterInternal method, but also after each test failure. In order to achieve this, we need to reset the cluster afterwards, when we get to know about both of the events (problem in afterInternal and test failure), and before resetting the currentCluster. Introduced a TestRule that keeps track of test failures and allows to execute arbitrary tasks when a test fails and when a test is completed (regardless of its result). Allows also to force the execution of the failure task (used in case of afterInternal issues rather than actual test failure).
Also updated ElasticsearchRestTests to make sure that the RestClient gets re-initialized in case we restart the suite cluster, otherwise all the subsequent tests fail. Improved this mechanism also to relate it directly to the restart of the cluster instead of checking whether the addresses have changed, which doesn't work anyway as the new cluster will use the same addresses but the client needs to be recreated anyway.

Changed search_type docs to reflect that the `(dfs_)query_and_fetch` modes are an internal optimization and should not be specified explicitly by the user.

This commit modifies the Kernel32Library to use direct mapping instead of a proxy class when doing native calls on Windows platforms. It also adds the "createSecurityManager" permission to the tests.policy file, and adds unit tests that should have failed when the Java security manager is enabled.
