When a node sends a join request to the master, only send back the response after it has been added to the master cluster state and published.
This will fix the rare cases where today, a join request can return, and the master, since its under load, have not yet added the node to its cluster state, and the node that joined will start a fault detect against the master, failing since its not part of the cluster state.
Since now the join request is longer, also increase the join request timeout default.

Previously, one MLT query per field was created for each item. One issue with
this method is that the maximum number of selected terms was equal to the
number of items times 'max_query_terms'. Instead, users should have direct control
over the maximum number of selected terms allowed, regardless of the number of
queried items.
Another issue related to the previous method is that it could lead to the
selection of rather uninteresting terms, that because they were found in a
particular queried item. Instead, this new procedure enforces the selection of
interesting terms across ALL items, not within each item. This could lead to
search results where the best matching items share commonalities amongst the
best characteristics of all the items.

This commit adds checks for nocommit and tabs in the source code.
The task is executed during the validate phase and can be disabled via

* `english` returned the slow snowball English stemmer
* `porter2` returned the snowball Porter stemmer (v1)
* `portuguese` was used twice, preventing the second version from working
Changes:
* `english` now returns the fast PorterStemmer (for indices created from v1.3.0 onwards)
* `porter2` now returns the snowball English stemmer (for indices created from v1.3.0 onwards)
* `light_english` now returns the `kstem` stemmer (`kstem` still works)
* `portuguese_rslp` returns the PortugueseStemmer
* `dutch_kp` is a synonym for `kp`
Tests and docs updated

Bugs:
* "groups" and "types" were being ignored
* "completion_fields" as wildcards were not being resolved to fieldnames
Enhancements:
* Made "groups" and "types" support wildcards
* Added missing tests

In order to return more information to the client, in case a TransportClient
can not connect to the cluster, this commit adds logging and also returns the
configured nodes in the NoNodeAvailableException
Also a minor bug has been fixed, which propagated exceptions wrong, so that an
invalid request was actually tried on every node, if a regular connection failure
on the first node had happened.
Closes#6376
Our REST backwards compatibility tests need to be able to disable client nodes within the TestCluster when running older tests that assume client nodes are not around.
Previously if the user provided a non-conforming string, it would blow up with
`java.lang.StringIndexOutOfBoundsException: String index out of range: -1`
which is not a *helpful* error message.
Also updated the documentation to make the possible setting values more clear.

A new "breadth_first" results collection mode allows upper branches of aggregation tree to be calculated and then pruned
to a smaller selection before advancing into executing collection on child branches.
Closes#6128
The put index template api supports the create parameter (defaults to false), which tells whether the template can replace an existing one with same name or not. Unified its behaviour between PUT and POST method, whereas the POST would previously force create to true.
Added create parameter to the rest spec (was missing before) and a REST test for create true scenario.
There is a pretty nasty bug in the lock factory we use that can cause
nodes to use the same data dir wiping each others data. Luckily this is
unlikely to happen if the nodes are running in different JVM which they
do unless they are embedded.

The _uid field wasn't available in a script despite it's always stored. Made it available and made available also _id and _type fields that are deducted from it.
Closes#6406
The versionMap holds all versions (keyed by _uid) for recently indexed
documents. Previously we only cleared it during flush, which can be
infrequent if the translog flush thresholds are high, and can cause
excessive heap usage especially for small documents.
Now we clear it during refresh which is usually more frequent
(e.g. once per second by default).
Closes#6379
The GeoBounds Aggregation is a new single bucket aggregation which outputs the coordinates of a bounding box containing all the points from all the documents passed to the aggregation as well as the doc count. Geobound Aggregation also use a wrap_logitude parameter which specifies whether the resulting bounding box is permitted to overlap the international date line. This option defaults to true.
This aggregation introduces the idea of MetricsAggregation which do not return double values and cannot be used for sorting. The existing MetricsAggregation has been renamed to NumericMetricsAggregation and is a subclass of MetricsAggregation. MetricsAggregations do not store doc counts and do not support child aggregations.
Closes#5634
This commit reverts the commit for issue #5900 introduced
in `1.2.0`. The unlimited translog size can cause memory pressure
on ES instances with low memory and high indexing load.
Closes#6377
Routing has been inadvertly changed in #5562 resulting in documents going to
different shards in 1.2. This is a terrible bug because an indexing request
would not necessarily go to the same shard anymore, potentially leading to
duplicates.
Close#6391
Previously, More Like This would create a new mlt query for each value of a
multi-value field. This could result in all the values of the field to be
selected, which defeats the purpose of More Like This. Instead, the correct
behavior is to generate only one mlt query for all the values of the field.
This commit provides the correct behavior for More Like This DSL. The fix for
More Like This API will be coming in another commit.
Closes#6310
The BigArrays limit is currently shared by the translog, netty, http and some
queries/aggregations. If any of these consumers starts taking a lot of memory,
then other ones might fail to allocate memory, which could have bad
consequences, eg. if ping requests can't be sent. The plan is to come up with
a better solution in 1.3.
Close#6332
If a polygon is constructed which overlaps the date line but has a hole which lies entirely one to one side of the date line, JTS error saying that the hole is not within the bounds of the polygon because the code which splits the polygon either side of the date line does not add the hole to the correct component of the final set of polygons. The fix ensures this selection happens correctly.
Closes#6179
