High Availability for JobTracker
--------------------------------
Key: MAPREDUCE-2648
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2648
Project: Hadoop Map/Reduce
Issue Type: New Feature
Reporter: Devaraj K
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
