> 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
