      Description

      When using the RMZKStateStore, if you restart the RM, you get a bunch of stack traces with messages like org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode = NodeExists for /rmstore. This is expected as these nodes already exist from before. We should catch these and print nicer messages.
