    Description

      In Hadoop cluster, JobTracker is responsible for managing the life cycle of MapReduce jobs. If JobTracker fails, then MapReduce service will not be available until JobTracker is restarted. We propose an automatic failover solution for JobTracker to address such single point of failure. It is based on Leader Election Framework suggested in ZOOKEEPER-1080

      Please refer to attached document.
