A small bug in the `IndexStatsCollector` can potentially returns statistics for newly created indices that does not exist yet in the collector's `ClusterState` local instance. It happens because an instance of the current `ClusterState` is captured and passed to all the collectors before they are executed (so that they all share the same view of the state of the cluster). On some clusters, if an index is created after the `ClusterState` is captured but before the `IndicesStatsRequest` is executed then it can appears in the index stats but have no corresponding entry in the local cluster state. This commit changes the IndexStatsCollector so that it only return statistics for indices that already exist in the cluster state. This way a consistent view is possible between indices/index/shard stats. Original commit: elastic/x-pack-elasticsearch@da173ae0b0
= 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.
