Subject Re: FileSystem Vs ZKStateStore for RM recovery
Date Wed, 11 Feb 2015 08:15:06 GMT
We recommend ZK-store, particularly if you plan to deploy multiple
ResourceManagers with failover. ZK-store ensures a single RM has write
access and thus is better protected against split-brain cases where both
RMs think they are active.
