Reported at: https://discuss.elastic.co/t/combine-elasticsearch-5-1-1-and-repository-hdfs/69659
If you define as described [in our docs](https://www.elastic.co/guide/en/elasticsearch/plugins/current/repository-hdfs-config.html) the following `elasticsearch.yml` settings:
```yml
repositories:
hdfs:
uri: "hdfs://es-master:9000/" # optional - Hadoop file-system URI
path: "some/path" # required - path with the file-system where data is stored/loaded
```
It fails at startup because we don't register the global setting `repositories.hdfs.path` in `HdfsPlugin`.
This PR removes that from our docs so people must provide those settings only when registering the repository with:
```
PUT _snapshot/my_hdfs_repository
{
"type": "hdfs",
"settings": {
"uri": "hdfs://namenode:8020/",
"path": "elasticsearch/respositories/my_hdfs_repository",
"conf.dfs.client.read.shortcircuit": "true"
}
}
```
Based on issue #22800.
Closes#22301
This commit removes the search type `dfs_query_and_fetch` without a
replacement. We don't allow to use this type via REST since 2.x
but still keep it around for no particular reason. There we no users
complaining about the availability. This should now be removed from the
codebase. `query_and_fetch` is still used internally to safe a roundtrip
if there is only one shard but it can't be used via the rest interface.
This is related to #22116. URLRepository requires SocketPermission
connect. This commit introduces a new module called "repository-url"
where URLRepository will reside. With the new module, permissions can
be removed from core.
Beforehand, the DateProcessor constructs its joda pattern formatter during processor
construction. This led to newly ingested documents being defaulted to
the year that the pipeline was constructed, not that of processing.
Fixes#22547.
Add unit tests for `TopHitsAggregator` and convert some snippets in
docs for `top_hits` aggregation to `// CONSOLE`.

Previous to his change when the range query was rewritten to an unbounded range (`[* TO *]`) it maintained the timezone and format for the query. This means that queries with different timezones and format which are rewritten to unbounded range queries actually end up as different entries in the search request cache.
This is inefficient and unnecessary so this change nulls the timezone and format in the rewritten query so that regardless of the timezone or format the rewritten query will be the same.
Although this does not fix#22412 (since it deals with the WITHIN case rather than the INTERSECTS case) it is born from the same arguments
These files should have been removed in an earlier commit. This commit also simplifies usage of ProgressLoggerWrapper by using the Groovy delegation instead of using explicit delegation.
5.3.0 is the first version that contains the split from headers to metadata, updated the check to reflect that. It was previously after to be able to commit to master first, and only after that backport the change. Otherwise master tests would have failed until the change was backported.
Previously the behavior where the `OpType` byte was serialized was only in
master, but it was recently backported to 5.x, so the serialization version
checks need to be updated as well.
This adds the necessary `AuthCache` needed to support preemptive authorization. By adding every host to the cache, the automatically added `RequestAuthCache` interceptor will add credentials on the first pass rather than waiting to do it after _each_ anonymous request is rejected (thus always sending everything twice when basic auth is required).
move "es." internal headers to separate metadata set in ElasticsearchException and stop returning them as response headers
Closes#17593
* [TEST] remove ESExceptionTests, move its methods to ElasticsearchExceptionTests or ExceptionSerializationTests
Docker cgroups are mounted in the wrong place (i.e., inconsistently with
/proc/self/cgroup). This commit adds an undocumented hack for working
around, for now.

As a follow up to #22649, this changes the resent tests for parsing parts of search
responses to randomly set the humanReadable() flag of the XContentBuilder that
is used to render the responses. This should help to test that we can parse back
thoses classes if the user specifies `?human=true` in the request url.
Instead of using Gradle-version specific compilation options, use distinct source sets. This also allows compilation of buildSrc/build-tools under IDEs that
don't understand the version-specific compilation options.

This changes build files so that building Elasticsearch works with both Gradle 2.13 as well as higher versions of Gradle (tested 2.14 and 3.3), enabling a smooth transition from Gradle 2.13 to 3.x.
In some cases (apparently with outlook files), mime4j library is needed.
We removed it in the past which can cause elasticsearch to crash when you are using ingest-attachment (and probably mapper-attachments as well in 2.x series) with a file which requires this library.
Similar problem as the one reported at #22077.
This commit replaces specialized functional interfaces in various
plugins with generic options. Instead of creating `StorageRunnable`
interfaces in every plugin we can just use `Runnable` or `CheckedRunnable`.
There was a typo in the `ParseField` declaration. I know
we want to port these parsers to `ObjectParser` eventually
but I don't have the energy for that today and want to get
this fixed.
Closes#22722
When users need to specify a custom location for configuration files,
they also need to specify a custom location for the jvm.options file yet
our docs are absent in this regard. This commit adds a note to the
rolling upgrade docs explaining this situation.

* Add top hits collapsing to search request
The field collapsing is done with a custom top docs collector that "collapse" search hits with same field value.
The distributed aspect is resolve using the two passes that the regular search uses. The first pass "collapse" the top hits, then the coordinating node merge/collapse the top hits from each shard.
```
GET _search
{
"collapse": {
"field": "category",
}
}
```
This change also adds an ExpandCollapseSearchResponseListener that intercepts the search response and expands collapsed hits using the CollapseBuilder#innerHit} options.
The retrieval of each inner_hits is done by sending a query to all shards filtered by the collapse key.
```
GET _search
{
"collapse": {
"field": "category",
"inner_hits": {
"size": 2
}
}
}
```
Adds the `VIEW IN CONSOLE` and `COPY AS CURL` links to the snippets
in the `value_count` docs and causes the build to execute the snippets
for testing.
Release #18160
To effectively allow a plugin to intercept a transport handler it needs
to know if the handler must be executed even if there is a rejection on the
thread pool in the case the wrapper forks a thread to execute the actual handler.
This adds the `VIEW IN CONSOLE` and `COPY AS CURL` links to the
snippets in the docs for the `date_range` aggregation and tests
those snippets as part of the build.

This commit adds a SpecialPermission constant and uses that constant
opposed to introducing new instances everywhere.
Additionally, this commit introduces a single static method to check that
the current code has permission. This avoids all the duplicated access
blocks that exist currently.
Today `InternalEngine#innerIndex` is a pretty big method (> 150 SLoC). This
commit merged `#index` and `#innerIndex` and splits it up into smaller contained
methods.
* Upgrade to Lucene 6.4.0
`ValueSource`s are now converted to `DoubleValueSource`s using the Lucene adapter made for the migration to the new API in 6.4.0.
Introduce CheckedSupplier and CheckedRunnable functional interfaces
into core. These offer a checked version of the Supplier and Runnable
interfaces for use with lambda apis.
