Labels: flip-6 (was: )
> Implement Yarn HA Services
> --------------------------
>
> Key: FLINK-5254
> URL: https://issues.apache.org/jira/browse/FLINK-5254
> Project: Flink
> Issue Type: Sub-task
> Components: YARN
> Reporter: Stephan Ewen
> Labels: flip-6
>
> The Yarn HighAvailability Services should be
> **Default**
> - This option takes the YARN Application's working directory as HA storage
> - It automatically uses that working directory for the BlobStore
> - It creates a HDFS based "RunningJobsRegistry" (see below)
> - ResourceManager leader election has a pre-configured leader, via the
> configuration, pointing to the AppMaster address.
> **ZooKeeper Based**
> - The ZooKeeper based services use ZooKeeper for the ResourceManager and
> JobManager leader election. That way, they are safe against network partition
> scenarios that otherwise lead to "split brain" situations
> A prototype for the simple "single job" {{RunningJobsRegistry}} based on HDFS
> is here:
