Some tests use AbstractIntegrationTest#indexRandom which sometimes uses async
indexing. This can easily run into queue size based rejections on a slow
box. In that case we should retry blocked indexing.
Now that we properly fixed the ability to set the queue size on the index / bulk thread pool, we should actually set them to a somehow reasonable value to protect from users potentially overflowing our system.
I suggest defaults to be 50 for bulk, and 200 for indexing.
Also, set the thread pool for get, which we should set (in a similar value to a "read" queue size we have today).

We want to make sure that Plugin Manager still downloading plugins from internet.
New tests requires internet access (`@Network` annotation has been added).
By default, tests annotated with `@Network` are not launched.
If you need to run these tests, use `-Dtests.network=true` option.
Closes#3894.
This commit adds support for random merge policies set for every
index created in an AbstractIntegrationTest. It will either set
'logbyte', 'logdoc' or 'tiered' merge policy as well as a random
value for compound files.
Added checks to IndexRequest#source(Object...) to ensure and even number
of parameters. This method otherwise throws an AIOOBException which is
confusing to users and doesn't report the root cause of the problem.
This commit allows for using Lucene doc values as a backend for field data,
moving the cost of building field data from the refresh operation to indexing.
In addition, Lucene doc values can be stored on disk (partially, or even
entirely), so that memory management is done at the operating system level
(file-system cache) instead of the JVM, avoiding long pauses during major
collections due to large heaps.
So far doc values are supported on numeric types and non-analyzed strings
(index:no or index:not_analyzed). Under the hood, it uses SORTED_SET doc values
which is the only type to support multi-valued fields. Since the field data API
set is a bit wider than the doc values API set, some operations are not
supported:
- field data filtering: this will fail if doc values are enabled,
- field data cache clearing, even for memory-based doc values formats,
- getting the memory usage for a specific field,
- knowing whether a field is actually multi-valued.
This commit also allows for configuring doc-values formats on a per-field basis
similarly to postings formats. In particular the doc values format of the
_version field can be configured through its own field mapper (it used to be
handled in UidFieldMapper previously).
Closes#3806
Migrate SearchContext.Rewrite to Releasable. All the parent child queries are now implemented as Lucene queries and the state is kept in the Weight.
Completely disable caching for `has_child` and `has_parent` filters, this has never worked and it also can also never work. The matching docIds are cached per segment while the collection of parent ids is top level.
Closes#3822
* Merged segments are now warmed-up at the end of the merge operation instead
of _refresh, so that _refresh doesn't pay the price for the warm-up of merged
segments, which is often higher than flushed segments because of their size.
* Even when no _warmer is registered, some basic warm-up of the segments is
performed: norms, doc values (_version). This should help a bit people who
forget to register warmers.
* Eager loading support for the parent id cache and field data: when one
can't predict what terms will be present in the index, it is tempting to use
a match_all query in a warmer, but in that case, query execution might not be
much faster than field data loading so having a warmer that only loads field
data without running a query can be useful.
Closes#3819
I tried to install a plugin directly from disk, but used the wrong arguments. Totally my fault for not RTFM properly.
However, by following the instructions printed out by `bin/plugin`, I ended up deleting my $ES/bin directory.
```
$ pwd
/tmp/elasticsearch-0.90.5
$ ls
LICENSE.txt NOTICE.txt README.textile bin config lib
$ bin/plugin --install file:///tmp/foo.zip
-> Installing file:///tmp/foo.zip...
Failed to install file:///tmp/foo.zip, reason: plugin directory /tmp/elasticsearch-0.90.5/plugins already exists. To update the plugin, uninstall it first using -remove file:///tmp/foo.zip command
$ bin/plugin -remove file:///tmp/foo.zip
-> Removing file:///tmp/foo.zip
Removed file:///tmp/foo.zip
$ ls
LICENSE.txt NOTICE.txt README.textile config lib
```
I reproduced the problem in 0.90.5 and the latest master.
Closes#3847.
Adding the mappers first could cause the wrong FieldMappers to be used during object parsing
Also:
Removed MergeContext.newFieldMappers, MergeContext.newObjectMappers and relatives as they are not used anymore.
Similarly removed MergeContext.addFieldDataChange & fieldMapperChanges as they were not used.
Closes#3844
Due to a change in 0.90 some exceptions may show up when starting a river,
even though this is not a problem as the shard has not been initialized
yet and a retry is scheduled.
Only valid fields (input, output, weight and payload) are now allowed inside a completion field.
This makes sure that typos like "inputs" are caught on indexing.
