    Description

      Fencing in ZK store kicks in when the RM tries to write something to the store. If the RM doesn't write anything to the store, it doesn't get fenced and can continue to assume being the Active.

      By periodically writing a file (say, every RM_ZK_TIMEOUT_MS seconds), we can ensure it gets fenced.
