Jason Lowe created MAPREDUCE-6230:
-------------------------------------

             Summary: MR AM does not survive RM restart if RM activated a new AMRM secret
key
                 Key: MAPREDUCE-6230
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6230
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am
            Reporter: Jason Lowe
            Assignee: Jason Lowe
            Priority: Blocker


A MapReduce AM will fail to reconnect to an RM that performed restart in the following scenario:

# MapReduce job launched with AMRM token generated from AMRM secret X
# RM rolls new AMRM secret Y and activates the new key
# RM performs a work-preserving restart
# MapReduce job AM now unable to connect to RM with "Invalid AMRMToken" exception
