> 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: https://github.com/StephanEwen/incubator-flink/commit/aaa2d7758797b2d6c9b6da42be6a5c4989468e3b
