Migrated from ES-Hadoop. Contains several improvements regarding:
* Security
Takes advantage of the pluggable security in ES 2.2 and uses that in order
to grant the necessary permissions to the Hadoop libs. It relies on a
dedicated DomainCombiner to grant permissions only when needed only to the
libraries installed in the plugin folder
Add security checks for SpecialPermission/scripting and provides out of
the box permissions for the latest Hadoop 1.x (1.2.1) and 2.x (2.7.1)
* Testing
Uses a customized Local FS to perform actual integration testing of the
Hadoop stack (and thus to make sure the proper permissions and ACC blocks
are in place) however without requiring extra permissions for testing.
If needed, a MiniDFS cluster is provided (though it requires extra
permissions to bind ports)
Provides a RestIT test
* Build system
Picks the build system used in ES (still Gradle)
This commit adds the following:
* SpatialStrategy documentation to the geo-shape reference docs.
* Updates relation documentation to geo-shape-query reference docs.
* Updates GeoShapeFiledMapper to set points_only to true if TERM strategy is used (to be consistent with documentation)
This option allows to force the xcontent type to use to store the `_source`
document. The default is to use the same format as the input format.
This commit makes this option ignored for 2.x indices and rejected for 3.0
indices.
As a replacement use ExistsQueryBuilder inside a mustNot() clause.
So instead of using `new ExistsQueryBuilder(name)` now use:
`new BoolQueryBuilder().mustNot(new ExistsQueryBuilder(name))`.
Closes#14112
This makes some minor improvements (does not fix all problems!)
It reorders unicast disco in elasticsearch.yml to be right after the network host,
for better locality.
It removes the warning (unreleased) about publish addresses, lets try to really discourage setting
that unless you need to (behind a proxy server). Most people should be fine with `network.host`
Finally it reorganizes the network docs page a bit:
We add a table of 4 "basic" settings at the very beginning:
* network.host
* discovery.zen.ping.unicast.hosts
* http.port
* transport.tcp.port
The first two being the most important, which addresses to bind and talk to, and the other two
being the port numbers.
The rest of the stuff I tried to simplify and reorder under "advanced" headers.
This is just a quick stab, I still think we need more effort into this thing, but we gotta start somewhere.
The NodeBuilder is currently used to construct a Node. However, this is
really just yet-another-builder that wraps around a Settings.Builder
witha couple convenience methods. But there are very few uses of these
convenience methods. This change removes NodeBuilder, in favor of just
using the Node constructor.
throw exception if a copy_to is within a multi field
Copy to within multi field is ignored from 2.0 on, see #10802.
Instead of just ignoring it, we should throw an exception if this
is found in the mapping when a mapping is added. For already
existing indices we should at least log a warning.
We remove the copy_to in any case.

When using S3 or EC2, it was possible to use a proxy to access EC2 or S3 API but username and password were not possible to be set.
This commit adds support for this. Also, to make all that consistent, proxy settings for both plugins have been renamed:
* from `cloud.aws.proxy_host` to `cloud.aws.proxy.host`
* from `cloud.aws.ec2.proxy_host` to `cloud.aws.ec2.proxy.host`
* from `cloud.aws.s3.proxy_host` to `cloud.aws.s3.proxy.host`
* from `cloud.aws.proxy_port` to `cloud.aws.proxy.port`
* from `cloud.aws.ec2.proxy_port` to `cloud.aws.ec2.proxy.port`
* from `cloud.aws.s3.proxy_port` to `cloud.aws.s3.proxy.port`
New settings are `proxy.username` and `proxy.password`.
```yml
cloud:
aws:
protocol: https
proxy:
host: proxy1.company.com
port: 8083
username: myself
password: theBestPasswordEver!
```
You can also set different proxies for `ec2` and `s3`:
```yml
cloud:
aws:
s3:
proxy:
host: proxy1.company.com
port: 8083
username: myself1
password: theBestPasswordEver1!
ec2:
proxy:
host: proxy2.company.com
port: 8083
username: myself2
password: theBestPasswordEver2!
```
Note that `password` is filtered with `SettingsFilter`.
We also fix a potential issue in S3 repository. We were supposed to accept key/secret either set under `cloud.aws` or `cloud.aws.s3` but the actual code never implemented that.
It was:
```java
account = settings.get("cloud.aws.access_key");
key = settings.get("cloud.aws.secret_key");
```
We replaced that by:
```java
String account = settings.get(CLOUD_S3.KEY, settings.get(CLOUD_AWS.KEY));
String key = settings.get(CLOUD_S3.SECRET, settings.get(CLOUD_AWS.SECRET));
```
Also, we extract all settings for S3 in `AwsS3Service` as it's already the case for `AwsEc2Service` class.
Closes#15268.
Do not to load fields from _source when using the `fields` option.
Non stored (non existing) fields are ignored by the fields visitor when using the `fields` option.
Fixes#10783
Support * wildcard to retrieve stored fields when using the `fields` option.
Supported pattern styles are "xxx*", "*xxx", "*xxx*" and "xxx*yyy".
In the example we show an `exists` query inside a constant score query. While this is possible, it can mislead users to think it is necessary so we should remove it.
# Please enter a commit message to explain why this merge is necessary,
# especially if it merges an updated upstream into a topic branch.

# Lines starting with '#' will be ignored, and an empty message aborts
# the commit.
- moves calculation of the delay to a single place (ReplicaShardAllocator)
- reduces coupling between GatewayAllocator and RoutingService
- in master failover situations, elapsed delay time is forgotten
Closes#14808
At the time of geo_shape query conception, CONTAINS was not yet a supported spatial operation in Lucene. Since it is now available this commit adds ShapeRelation.CONTAINS to GeoShapeQuery. Randomized testing is included and documentation is updated.
We actually want to keep the test when using deprecated setting in 3.0.
We will keep this setting deprecated as well so people will be able to update in a smoother way.
Also add the deprecating information to the migration documentation.
Follow up for #13228.
This commit adds support for a secondary storage account:
```yml
cloud:
azure:
storage:
my_account1:
account: your_azure_storage_account1
key: your_azure_storage_key1
default: true
my_account2:
account: your_azure_storage_account2
key: your_azure_storage_key2
```
When creating a repository, you can choose which azure account you want to use for it:
```sh
curl -XPUT localhost:9200/_snapshot/my_backup1?pretty -d '{
"type": "azure"
}'
curl -XPUT localhost:9200/_snapshot/my_backup2?pretty -d '{
"type": "azure",
"settings": {
"account" : "my_account2",
"location_mode": "secondary_only"
}
}'
```
`location_mode` supports `primary_only` or `secondary_only`. Defaults to `primary_only`. Note that if you set it
to `secondary_only`, it will force `read_only` to true.
We already introduced the MatchNoneQueryBuilder query that does not
return any documents, mainly because we needed it for internal
representation of the NONE option in the IndicesQueryBuilder.
However, the query was requested at least once also for the query dsl,
and since we can parser it already we should document it as
`match_none` query in the relevant reference docs as well.
Some users may already be familiar with column stores, so saying more explicitly
that doc values are a columnar representation of the data may help them better
and/or more quickly understand what doc values are about.
This adds the `cluster.routing.allocation.total_shards_per_node`
setting, which limits the total number of shards across all indices on
each node. It defaults to -1 and can be dynamically configured.
Resolves#14456
The completion suggester provides auto-complete/search-as-you-type functionality.
This is a navigational feature to guide users to relevant results as they are typing, improving search precision.
It is not meant for spell correction or did-you-mean functionality like the term or phrase suggesters.
The completions are indexed as a weighted FST (finite state transducer) to provide fast Top N prefix-based
searches suitable for serving relevant results as a user types.
closes#10746
Current processors setting is not reflected in nodes info API
("os.available_processors"). Add os.allocated_processors to shows
actual number of processors that we are using.
query_binary and filter_binary are unused at this point, as we only parse on the coordinating node and the java api only holds structured java objects for queries and filters, meaning they all implement Writeable and get natively serialized.
Relates to #14308Closes#14433
This commit forbids the changing of thread pool types for any thread
pool. The motivation here is that these are expert settings with
little practical advantage.
