-------------------------------

             Summary: Make changes for RM restart phase 1
                 Key: YARN-230
                 URL: https://issues.apache.org/jira/browse/YARN-230
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha
            Assignee: Bikas Saha


As described in YARN-128, phase 1 of RM restart puts in place mechanisms to save application
state and read them back after restart. Upon restart, the NM's are asked to reboot and the
previously running AM's are restarted.
After this is done, RM HA and work preserving restart can continue in parallel. For more details
please refer to the design document in YARN-128
