Zachary Tong df88ba4ed7 [Rollup] Don't persist state if aborting
`doSaveState` can be invoked on different types of failure.  Some of
these failures are recoverable (e.g. search exception) which just cause
the job to reset until the next trigger time.  Other exceptions might
be caused by an Abort request.

Previously `doSaveState` assumed that the indexer state would be
INDEXING, STOPPED or STARTED and asserted that.  But if we are ABORTING
it failed the assertion, and in production would try to persist
that aborting state which is not needed (and may complicate matters later).

This commit removes the assertion and only tries to persist if we
are not aborting.  If we're aborting, we just invoke the next handler
which is likely an onFailure handler.

= Elasticsearch X-Pack

A set of Elastic's commercial plugins for Elasticsearch:

- License
- Security
- Watcher
- Monitoring
- Machine Learning
- Graph

= Setup

You must checkout `x-pack-elasticsearch` and `elasticsearch` with a specific directory structure. The
`elasticsearch` checkout will be used when building `x-pack-elasticsearch`. The structure is:

- /path/to/elastic/elasticsearch
- /path/to/elastic/elasticsearch-extra/x-pack-elasticsearch

== Vault Secret

The build requires a Vault Secret ID. You can use a GitHub token by following these steps:

1. Go to https://github.com/settings/tokens
2. Click *Generate new token*
3. Set permissions to `read:org`
4. Copy the token into `~/.elastic/github.token`
5. Set the token's file permissions to `600`

```
$ mkdir ~/.elastic
$ vi ~/.elastic/github.token
# Add your_token exactly as it is into the file and save it
$ chmod 600 ~/.elastic/github.token
```

If you do not create the token, then you will see something along the lines of this as the failure when trying to build X-Pack:

```
* What went wrong:
Missing ~/.elastic/github.token file or VAULT_SECRET_ID environment variable, needed to authenticate with vault for secrets
```

=== Offline Mode

When running the build in offline mode (`--offline`), it will not required to have the vault secret setup.

== Native Code

**This is mandatory as tests depend on it**

Machine Learning requires platform specific binaries, built from https://github.com/elastic/ml-cpp via CI servers.

= Build

- Run unit tests:
+
[source, txt]
-----
gradle clean test
-----

- Run all tests:
+
[source, txt]
-----
gradle clean check
-----

- Run integration tests:
+
[source, txt]
-----
gradle clean integTest
-----

- Package X-Pack (without running tests)
+
[source, txt]
-----
gradle clean assemble
-----

- Install X-Pack (without running tests)
+
[source, txt]
-----
gradle clean install
-----

= Building documentation

The source files in this repository can be included in either the X-Pack
Reference or the Elasticsearch Reference.

NOTE: In 5.4 and later, the Elasticsearch Reference includes X-Pack-specific
content that is pulled from this repo.

To build the Elasticsearch Reference on your local machine, use the `docbldes` 
or `docbldesx` build commands defined in
https://github.com/elastic/docs/blob/master/doc_build_aliases.sh

== Adding Images

When you include an image in the documentation, specify the path relative to the
location of the asciidoc file. By convention, we put images in an `images`
subdirectory.

For example to insert `watcher-ui-edit-watch.png` in `watcher/limitations.asciidoc`:

. Add an `images` subdirectory to the watcher directory if it doesn't already exist.
. In `limitations.asciidoc` specify:
+
[source, txt]
-----
 image::images/watcher-ui-edit-watch.png["Editing a watch"]
-----

Please note that image names and anchor IDs must be unique within the book, so
do not use generic identifiers.
