Simplify Sniffer initialization and automatically create the default HostsSniffer
Take Sniffer.Builder out to its own top level class. Remove HostsSniffer.Builder and let SnifferBuilder create the default HostsSniffer. This simplifies the Sniffer initialization as the HostsSniffer is not mandatory anymore. It can still be specified though in case the configuration needs to be changed or a different impl has to be used. Also make HostsSniffer an interface.
Performing the bulk request shown in #19267 now results in the following:
```
{"_index":"test","_type":"test","_id":"1","_version":1,"_operation":"create","forced_refresh":false,"_shards":{"total":2,"successful":1,"failed":0},"status":201}
{"_index":"test","_type":"test","_id":"1","_version":1,"_operation":"noop","forced_refresh":false,"_shards":{"total":2,"successful":1,"failed":0},"status":200}
```
This adds the `bin/elasticsearch-translate` bin file that will be used
for CLI tasks pertaining to Elasticsearch. Currently it implements only
a single sub-command, `truncate-translog`, that creates a truncated
translog for a given folder.
Here's what running the tool looks like:
```
λ bin/elasticsearch-translog truncate -d data/nodes/0/indices/P45vf_YQRhqjfwLMUvSqDw/0/translog/

It also includes a `-b` batch operation that can be used to skip the
confirmation diaglog.
Resolves#19123
This change adds a new special path to the buckets_path syntax
`_bucket_count`. This new option will return the number of buckets for a
multi-bucket aggregation, which can then be used in pipeline
aggregations.
Closes#19553
When the request body is missing, all documents in the target index are counted.
As mentioned in #19422, the same should happen when the request body is an empty
json object. This is also the behaviour for the `_search` endpoint and the two
APIs should behave in the same way.
Before the aggregation tree was traversed to figure out what the parent level is, this commit
changes that by using `NestedScope` to figure out the nested depth level. The big upsides
are that this cleans up `NestedAggregator` (it used a hack to lazily figure out the nested parent filter)
and this is also what `nested` query uses and therefor the `nested` query can be included inside `nested`
aggregation and work correctly.
Closes#11749Closes#12410
Recently, we experience timeouts on our Windows build slaves for
Netty4RestIT. Until we have figured out what's going on, we
increase this test suite's timeout temporarily to ensure this
timeout does not mask other problems.
We disable transitive dependencies in our build plugin
for all dependencies except for the group `org.elasticsearch`.
However, in the reindex plugin we depend on the REST client
and declare its dependencies again which is not necessary
(and led to problems with conflicting versions in #19281).
With this PR we remove the duplicate declaration.
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.
Closes#19079
This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
This adds new circuit breaking with the "request" breaker, which adds
circuit breaks based on the number of buckets created during
aggregations. It consists of incrementing during AggregatorBase creation
This also bumps the REQUEST breaker to 60% of the JVM heap now.
The output when circuit breaking an aggregation looks like:
```json
{
"shard" : 0,
"index" : "i",
"node" : "a5AvjUn_TKeTNYl0FyBW2g",
"reason" : {
"type" : "exception",

Relates to #14046
Messy tests with mustache were either moved to core, moved to a rest test or remained untouched if they actually tested mustache.
Also removed tests that were redundant.
After #13834 many tests that used Groovy scripts (for good or bad reason) in their tests have been moved in the lang-groovy module and the issue #13837 has been created to track these messy tests in order to clean them up.
This commit moves more tests back in core, removes the dependency on Groovy, changes the scripts in order to use the mocked script engine, and change the tests to integration tests.
This change renames the package org.elasticsearch.search.fetch.fielddata in org.elasticsearch.search.fetch.docvalues and renames the
FieldData* classes in DocValue*. This is a follow up of the renaming that happened in #18943
In #15950#15080#16084 we added the support of TimeOut for Requests with a default client`setTimeoutIntervalInMs`.
So we can remove this useless todo which was added for only one method.
Closes#18617.
Azure and Google cloud blob containers, as the APIs for both return
a 404 in the case of a missing object, which we already handle through
a NoSuchFileFoundException.
With #19140 we started persisting the node ID across node restarts. Now that we have a "stable" anchor, we can use it to generate a stable default node name and make it easier to track nodes over a restarts. Sadly, this means we will not have those random fun Marvel characters but we feel this is the right tradeoff.
On the implementation side, this requires a bit of juggling because we now need to read the node id from disk before we can log as the node node is part of each log message. The PR move the initialization of NodeEnvironment as high up in the starting sequence as possible, with only one logging message before it to indicate we are initializing. Things look now like this:
```

Needless to say, settings `node.name` explicitly still works as before.
The commit also contains some clean ups to the relationship between Environment, Settings and Plugins. The previous code suggested the path related settings could be changed after the initial Environment was changed. This did not have any effect as the security manager already locked things down.

Reading the best practices [recommended by AWS](http://docs.aws.amazon.com/java-sdk/latest/developer-guide/credentials.html), we should use `DefaultAWSCredentialsProviderChain` instead of providing the detail of the chain ourselves.
For now, we read credentials (if not provided in `elasticsearch.yml`) using:
```java
credentials = new AWSCredentialsProviderChain(
new SystemPropertiesCredentialsProvider(),
new EnvironmentVariableCredentialsProvider(),
new InstanceProfileCredentialsProvider()
);
```
Which means that we read from:
* Environment Variables - `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` (RECOMMENDED since they are recognized by all the AWS SDKs and CLI except for .NET), or `AWS_ACCESS_KEY` and `AWS_SECRET_KEY` (only recognized by Java SDK)
* Java System Properties - `aws.accessKeyId` and `aws.secretKey`
* Instance profile credentials delivered through the Amazon EC2 metadata service
Using instead:
```java
credentials = new DefaultAWSCredentialsProviderChain();
```
Will give us two new more methods out of the box:
> * Credential profiles file at the default location (`~/.aws/credentials`) shared by all AWS SDKs and the AWS CLI
> * Credentials delivered through the Amazon EC2 container service if `AWS_CONTAINER_CREDENTIALS_RELATIVE_URI` environment variable is set and security manager has permission to access the variable
Cherry on the cake: as soon as AWS SDK will propose a new implementation, we will benefit from it without any modification (just updating the SDK).
We also simplify
```
new AWSCredentialsProviderChain(new StaticCredentialsProvider(new BasicAWSCredentials(key, secret)));
```
As there is no need to wrap StaticCredentialsProvider in AWSCredentialsProviderChain.
Closes#19556.
Follow up for #18662 and #18690.
* For consistency, we rename method parameters and use `key` and `secret` instead of `account` and `key`.
* We add some tests to check that settings are correctly applied.
* Tests revealed that some checks are bad like for #18662.
Add test and fix issue for getting the right S3 endpoint
Test when Repository, Repositories or global settings are defined
But ignore testAWSCredentialsWithSystemProviders test
Add tests for AWS Client Configuration
Fix NPE when no region is set
We used to transform region="" to region=null but it's not needed anymore and would actually cause NPE from now.
Follow up for #18662
We add some tests to check that settings are correctly applied.
Tests revealed that some checks were missing.
But we ignore `testAWSCredentialsWithSystemProviders` test for now.
It can happen that the list of healthy hosts is empty, then we get one from the blacklist. but some other operation might have sneaked in and emptied the blacklist in the meantime, so we have to retry till we manage to get some host, either from the healthy list or from the blacklist.
