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. -- This message was sent by Atlassian JIRA (v6.2#6252)
