This commit clarifies the behavior that must be adhered to by any
implementors of the BlobContainer interface. This is done through
expanded Javadocs.

This adds a low level primitive operations to shrink an existing
index into a new index with a single shard. This primitive expects
all shards of the source index to allocated on a single node. Once the target index is initializing on the shrink node it takes a snapshot of the source index shards and copies all files into the target indices data folder. An [optimization](https://issues.apache.org/jira/browse/LUCENE-7300) coming in Lucene 6.1 will also allow for optional constant time copy if hard-links are supported by the filesystem. All mappings are merged into the new indexes metadata once the snapshots have been taken on the merge node.
To shrink an existing index all shards must be moved to a single node (one instance of each shard) and the index must be read-only:
```BASH
$ curl -XPUT 'http://localhost:9200/logs/_settings' -d '{
"settings" : {
"index.routing.allocation.require._name" : "shrink_node_name",
"index.blocks.write" : true
}
}
```
once all shards are started on the shrink node. the new index can be created via:
```BASH
$ curl -XPUT 'http://localhost:9200/logs/_shrink/logs_single_shard' -d '{
"settings" : {
"index.codec" : "best_compression",
"index.number_of_replicas" : 1
}
}'
```
This API will perform all needed check before the new index is created and selects the shrink node based on the allocation of the source index. This call returns immediately, to monitor shrink progress the recovery API should be used since all copy operations are reflected in the recovery API with byte copy progress etc.
The shrink operation does not modify the source index, if a shrink operation should
be canceled or if the shrink failed, the target index can simply be deleted and
all resources are released.
This PR changes the InternalTestCluster to support dedicated master nodes. The creation of dedicated master nodes can be controlled using a new `supportsMasterNodes` parameter to the ClusterScope annotation. If set to true (the default), dedicated master nodes will randomly be used. If set to false, no master nodes will be created and data nodes will also be allowed to become masters. If active, test runs will either have 1 or 3 masternodes

This change makes ES compile with java9 again, build 118.
* There are a handful of changes due to failure to determine types during compile.
* The attachment plugins which use tika needed to have tika upgraded in order to pickup fixes there for java 9.
* azure discovery and s3 repository indirectly depend on jaxb, which is no longer in the default modules. They now add a jaxb dependency externally, and make JarHell allow for this package.
* ESBlobStore tests must move to the test framework if we want to be able to reuse them in the context of plugins.
* To be able to identify more easily what are Integration Tests vs Unit Tests, this commit renames `*AzureTestCase` to `*AzureIntegTestCase`.
* Move some debug level logs to trace level
* Collapse when possible identical catch blocks
* `blobNameFromUri()` does not need anymore to get the container name. We just split the URI after 3 `/` and simply get the remaining part.
* Added a Unit test for that
* As we renamed some existing classes, checkstyle is now complaining about the lines width.
* While we are at it, let's replace all calls to `execute().actionGet()` with `get()`
* Move `readSettingsFromFile()` in a Util class. Note that this class might be useful for other plugins (S3/EC2/Azure-discovery for instance) so may be we should move it to the test framework?
* Replace some part of the code with lambdas
This commit fixes the inequality symbol used in a test assertion in
RepositoryS3SettingsTests#testInvalidChunkBufferSizeRepositorySettings. The
inequality symbol was previously backwards but fixed in commit
cad0608cdb but fixing the inequality
symbol here was missed in that commit.
Closes#18449
Probably when we updated Azure SDK, we introduced a regression.
Actually, we are not able to remove files anymore.
For example, if you register a new azure repository, the snapshot service tries to create a temp file and then remove it.
Removing does not work and you can see in logs:
```
[2016-05-18 11:03:24,914][WARN ][org.elasticsearch.cloud.azure.blobstore] [azure] can not remove [tests-ilmRPJ8URU-sh18yj38O6g/] in container {elasticsearch-snapshots}: The specified blob does not exist.
```
This fix deals with that. It now list all the files in a flatten mode, remove in the full URL the server and the container name.
As an example, when you are removing a blob which full name is `https://dpi24329.blob.core.windows.net/elasticsearch-snapshots/bar/test` you need to actually call Azure SDK with `bar/test` as the path, `elasticsearch-snapshots` is the container.
To run the test, you need to pass some parameters: `-Dtests.thirdparty=true -Dtests.config=/path/to/elasticsearch.yml`
Where `elasticsearch.yml` contains something like:
```
cloud.azure.storage.default.account: account
cloud.azure.storage.default.key: key
```
Related to #16472Closes#18436.
This change does the following:
- Queries that are currently unsupported such as prefix queries on numeric
fields or term queries on geo fields now throw an error rather than returning
a query that does not match anything.
- Fuzzy queries on numeric, date and ip fields are now unsupported: they used
to create range queries, we now expect users to use range queries directly.
Fuzzy, regexp and prefix queries are now only supported on text/keyword
fields (including `_all`).
- The `_uid` and `_id` fields do not support prefix or range queries anymore as
it would prevent us to store them more efficiently in the future, eg. by
using a binary encoding.
Note that it is still possible to ignore these errors by using the `lenient`
option of the `match` or `query_string` queries.
Previously multiple extensions could be provided, however, this can lead
to confusion with on-disk scripts (ie, "foo.js" and "foo.javascript")
having different content. Only a single extension is now supported.
The only language currently supporting multiple extensions was the
Javascript engine ("js" and "javascript"). It now only supports the
`.js` extension.
Relates to #10598
This removes all the mentions of the sandbox from the script engine
services and permissions model. This means that the following settings
are no longer supported:
```yaml
script.inline: sandbox
script.stored: sandbox
```
Instead, only a `true` or `false` value can be specified.
Since this would otherwise break the default-allow parameter for
languages like expressions, painless, and mustache, all script engines
have been updated to have individual settings, for instance:
```yaml
script.engine.groovy.inline: true
```
Would enable all inline scripts for groovy. (they can still be
overridden on a per-operation basis).
Expressions, Painless, and Mustache all default to `true` for inline,
file, and stored scripts to preserve the old scripting behavior.
Resolves#17114
I am unable to set ec2 discovery tags because this setting was
accidentally omitted from the register settings list in
Ec2DiscoveryPlugin.java. I get this:
java.lang.IllegalArgumentException: unknown setting [discovery.ec2.tag.project]
This removes dead/duplicate code and makes the `_index` field not configurable.
(Configuration used to jus be ignored, now we would throw an exception if any
is provided.)
Most of the current implementations of BaseNodesResponse (plural Nodes) ignore FailedNodeExceptions.
- This adds a helper function to do the grouping to TransportNodesAction
- Requires a non-null array of FailedNodeExceptions within the BaseNodesResponse constructor
- Reads/writes the array to output
- Also adds StreamInput and StreamOutput methods for generically reading and writing arrays
QueryBuilder has generics, but those are never used: all call sites use
`QueryBuilder<?>`. Only `AbstractQueryBuilder` needs generics so that the base
class can contain a default implementation for setters that returns `this`.
This commit introduces a handshake when initiating a light
connection. During this handshake, node information, cluster name, and
version are received from the target node of the connection. This
information can be used to immediately validate that the target node is
a member of the same cluster, and used to set the version on the
stream. This will allow us to extend APIs that are used during initial
cluster recovery without a major version change.

This commit removes the method Strings#splitStringToArray and replaces
the call sites with invocations to String#split. There are only two
explanations for the existence of this method. The first is that
String#split is slightly tricky in that it accepts a regular expression
rather than a character to split on. This means that if s is a string,
s.split(".") does not split on the character '.', but rather splits on
the regular expression '.' which splits on every character (of course,
this is easily fixed by invoking s.split("\\.") instead). The second
possible explanation is that (again) String#split accepts a regular
expression. This means that there could be a performance concern
compared to just splitting on a single character. However, it turns out
that String#split has a fast path for the case of splitting on a single
character and microbenchmarks show that String#split has 1.5x--2x the
throughput of Strings#splitStringToArray. There is a slight behavior
difference between Strings#splitStringToArray and String#split: namely,
the former would return an empty array in cases when the input string
was null or empty but String#split will just NPE at the call site on
null and return a one-element array containing the empty string when the
input string is empty. There was only one place relying on this behavior
and the call site has been modified accordingly.
When working on #18008 I found while reading the code that we don't filter anymore `repositories.s3.access_key` and `repositories.s3.secret_key`.
Also fixed a typo in REST test
Lucene allows to create a ICUTokenizer with a special config argument
enabling the customization of the rule based iterator by providing
custom rules files.
This commit enable this feature. Users could provide a list of RBBI rule
files to ICU tokenizer.
