- adds support for multiple logging configurations under the config dir (will pick up any logging.xxx in the config folder tree)
- plugins can now define a top level config directory that will be copied under es config dir and will be renamed after the plugin name (same as the support we have the plugin "bin" dirs)
Closes#6802
There is a special type of request that tries to not allocate another buffer when sending bytes request (used by the public cluster state action). With the new pages bytes reference support, the content can already be a composite channel buffer, take that into account when building the actual composite buffer that will be sent over the network

When launching multiple nodes in MS Windows env, batch command window does not come by default with any title.
This patch add `Elasticsearch VERSION` as a title, where VERSION is the current elasticsearch version.
Same for `plugin.bat` and `service.bat`.

Today, if we miss on a get on setting, we try its camel case version. The assumption is that in our code, we never use camel case to lookup a setting, but we want to support camel case if the user provided one.
This can be expensive (#toCamelCase) when the get on the setting is done in a tight call, which is evident when running the allocation deciders as part of the reroute logic.
Instead of doing the camel case check on get, prepare an additional map that includes all the settings that are provided as came case, and try and lookup from it if needed.

At the moment one can iterate the MapperService to go through all document mappers. This includes the document mapper of DEFAULT_MAPPING, which may be surprising and lead to unintended results. This commit removes the Iterable implementation and add a docMappers method that asks the caller to make an explicit choice
Closes#6793
We check if the version map needs to be refreshed after we released
the readlock which can cause the the engine being closed before we
read the value from the volatile `indexWriter` field which can cause an
NPE on the indexing thread. This commit also fixes a potential uncaught
exception if the refresh failed due to the engine being already closed.

remove internal callas on FieldMappers#Names, we properly reuse FieldMapper, so there is no need to try and call intern in order to reuse the names. This can be heavy with many fields and continuous mapping parsing.

We use awaitBusy in our tests, the problem is that we have to check if it awaited or not, and then try and keep around somehow more info around why the predicate failed and a timeout happened.
The idea of assertBusy is to allow to simply write "regular" test code, and if the test code trips, it will busy wait till a timeout. This allows us to keep around the assertion information and properly throw it for information that is inherently kept in the failure itself.
If you are indexing tiny documents then the previous default (5000)
was too low, causing excessive fsyncs with high indexing rates. With
this change we now only flush by byte size (200 MB) by default for
better indexing performance for tiny documents.
Closes#6783
When refresh_interval is long or disabled, and indexing rate is high,
it's possible for live version map to use non-trivial amounts of RAM.
With this change we now trigger a refresh in such cases to clear the
version map so we don't use unbounded RAM.
Closes#6443
Aggregation name are now able to use any character except '[', ']', and '>". Dot syntax may still be used to reference values (e.g. in the order field) but may only defence the value directly beneath the last aggregation in the list. more complex structures will need to be accessed using the aggname[value] syntax
Closes#6702
When a master receives a cluster state from another node, it compares the local cluster state with the one it got. If the local one has a higher version, it sends a JoinClusterRequest to the other master to tell it step down. Because our network layer is asymmetric, we need to make sure we're connected before sending.
Closes#6779
Concrete indices is now called multiple times when needed instead of changing what's inside the incoming request with the concrete indices. Ideally we want to keep the original aliases or indices or wildcard expressions in the request.
Also made sure that the check blocks is done against the concrete indices, which wasn't the case for delete index, delete mapping, open index, close index, types exists and indices exists.

In #6706 we change the master validation to start pining immediately after a new master as ellected or a node joined. The idea is to have a quicker response to failures. This does however create a problem if the new master has yet fully processed it's ellection and responds to the ping with a NoLongerMasterException. This causes the source node to remove the current master and ellect another, only to find out it's not a master either and so forth. We are moving this change to the feature/improve_zen branch, where the improvements we made will cause the situation to be handled properly.
This reverts commit ae16956e07.
This reverts:
"Test: Temporarily change delete/put_mapping to wait for green": commit e408f8f638c2dd97a3ec86c8a9ac940f43ab37a0.
"[TEST] wait for green to update mapping": commit b3641a2ee6eb23318d49f5f04b39149e70c2b65b.
The change added in #6762 helps making sure the pending mapping updates are processed on all nodes to prevent moving shards to nodes which are not yet fully aware of the new mapping. However it introduced a racing condition delete_mapping operations, potentially causing a type to be added after it's deletion. This commit solves this by only sending a mapping update if the mapping source has actually changed.
Closes#6772
the default mapping is not merged, but updated in place, and only put mapping API can change it, no need to make sure it has been properly updated on the master. This can cause conflicts when a put mapping for it happens at the same time.

When we know the ID for the document we are about to index was
auto-generated, we don't need to acquire/release the per-ID lock,
which might provide small speedups during highly concurrent indexing.
Closes#6584
In order to have access to all codecs and handlers by netty, they
need to be exposed during shading, otherwise only the classes, which
are used by the built are exposed.
The match_phrase_prefix provided the same explanation as the match_phrase
query. There was no indication that the last term was run as a prefix
query.
This change marks the last term (or terms if there are multiple terms
in the same position) with a *

During phase1 we copy over all lucene segments. These may refer to mapping updates that are still queued up to be sent to master. We must make sure those pending updates are processed before completing the relocation.
