Failing a parent breaker check is eventually consistent, so the test
could fail the parent limit, throw an exception, and before being
adjusted back down, increment more and throw a circuit breaking
exception on the child. This increases the child's limit, to ensure
we're only testing the parent limit.
It adds an additional assert to ensure that the breaker total is
correctly re-adjusted when the parent breaker has been tripped.
This does the following:
* Make 'force' flag only build a merge if the delegate MP returned no merges
* Add async handling for 'flush' when 'waitForMerges' is false
* Remove flush at the beginning of optimize. This is something the user can
do if they wish, before calling optimize.

Remove the creation of a node client if not there before each test through setup method. `numClientNodes` makes sure that the client node gets created during suite cluster initialization.
Previously, the only way to specify a document not present in the index was to
use `like_text`. This would usually lead to complex queries made of multiple
MLT queries per document field. This commit adds the ability to the MLT query
to directly specify documents not present in the index (artificial documents).
The syntax is similar to the Percolator API or to the Multi Term Vector API.
Closes#7725
Create client nodes using `node.client: true` instead of `node.data: false` and `node.master: false`.
We should create client nodes in our test infra using the `node.client:true` settings as that is the one that users use, and the one that we use as well in `ClientNodePredicate` thus we end up not finding client nodes otherwise as they weren't created with the proper setting.
Updated also the `DataNodePredicate` so that `client: true` is enough, no need for `data: false` as well.
Closes#7911
The minimum number of optional should clauses of the generated query to match
can now be set using the more extensive minimum should match syntax. This
makes the `percent_terms_to_match` parameter deprecated, and replaced in favor
to a new `minimum_should_match` parameter.
Closes#7898
With #7834, we simplified ZenDiscovery by making it use the current cluster state for all it's decision. This had the side effect a node may start it's Master FD before the master has fully processed that cluster state update that adds that node (or elects the master master). This is due to the fact that master FD is started when a node receives a cluster state from the master but the master it self may still be publishing to other node.
This commit makes sure that a master FD ping is only failed once we know that there is no current cluster state update in progress.
Closes#7908
It was only used by `readSource`, it has been changed to return a
Translog.Operation, which can have .getSource() called on it to return
the source. `readSource` has been removed.
This also removes the checked IOException, any exception thrown is
unexpected and should throw a runtime exception.
Moves the ReleasableBytesStreamOutput allocation into the body of the
try-catch block so the lock can be released in the event of an exception
during allocation.
Similar to #7856 but relates to the fetch shard level requests. We currently use the same internal request when we need to fetch within search and scroll. The two original requests though diverged after #6933 as SearchRequest implements IndicesRequest while SearchScrollRequest doesn't. That said, with #7319 we made `FetchSearchRequest` implement IndicesRequest by making it hold the original indices taken from the original request, which are null if the fetch was originated by a search scroll, and that is why original indices are optional there.
This commit introduces a separate fetch request and transport action for scroll, which doesn't hold original indices. The new action is only used against nodes that expose it, the previous action name will be used for nodes older than 1.4.0.Beta1.
As a result, in 1.4 we have a new `indices:data/read/search[phase/fetch/id/scroll]` action that is equivalent to the previous `indices:data/read/search[phase/fetch/id]` whose request implements now IndicesRequest and holds the original indices coming from the original request. The original indices in the latter request can only be null during a rolling upgrade (already existing version checks make sure that serialization is bw compatible), when some nodes are still < 1.4.
Closes#7870
The node fault detection class is used by the master node to ping the nodes in the cluster and verify they are alive. This PR simplifies the concurrency controls in the class + adds a test for a scenario that surfaced the problem.
Closes#7889
At the moment, ZenDiscovery contains a local copy of the disco nodes plus a flag that indicates whether the local node is master or not. This is redundant as the same information is stored in the cluster state. Have duplicate copy can lead to unneeded concurrency issues. This PR removes the duplication, including moving the ownership of the localNode creation to ClusterState
The PR introduces a tighter control of the background joining thread to make sure it is started and stopped together with any cluster state changes. This solves potentially concurrency bugs where a joining thread may fail to start.
Last we add a couple of safety checks to make sure that if a nodes receives a cluster state from a new master while actively trying to join another one (or electing itself) we go back to pinging to actively join it.
Closes#7834
The returned sets are only used for iterating. Therefore we might
as well return a list since this guaratees order.
This is the same effect as in

As pointed out in #7487 DocLookup is a variable that is accessible by all scripts
for one doc while the query is executed. But the _score and therfore the scorer
depends on the current context, that is, which part of query is currently executed.
Instead of setting the scorer for DocLookup
and have Script access the DocLookup for getting the score, the Scorer should just
be explicitely set for each script.
DocLookup should not have any reference to a scorer.
This was similarly discussed in #7043.
This dependency caused a stackoverflow when running script score in combination with an
aggregation on _score. Also the wrong scorer was called when nesting several script scores.

Incorrect usage of XContentParser.hasTextCharacters() can result in NumberFormatException as well as other possible issues in template query parser and phrase suggest parsers.
Fixes#7875
Today we only run 10% of the time, and the test doesn't fail when
corruption is detected.
I think it's better to always run and fail the test, so we can catch
any possible resiliency bugs in Lucene/Elasticsearch causing corruption.
For known tests that create corrupted indices, it's easy to set
MockFSDirectoryService.CHECK_INDEX_ON_CLOSE to false...

On the page http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-synonym-tokenfilter.html
even on a huge monitor the text is being wrapped the next way
```
mapping:
ipod, i-pod, i pod => ipod, i-pod, i pod
mapping:
ipod, i-pod, i pod => ipod
```
So one can think that "mapping:" is not in comment and is a part of syntax. But the lines are less than 80 chars, so perhaps the problem is in the page layout and there may be some other pages in the reference where the text is also being wrapped in an undesirable way.
Closes#7739
