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

             Summary: Add a customized uncaughtexceptionhandler for fair scheduler
                 Key: MAPREDUCE-6830
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6830
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: yarn
            Reporter: Yufei Gu
            Assignee: Yufei Gu


There are several threads in fair scheduler. The thread will quit when there is a runtime
exception inside it. We should bring down the RM when that happens. Otherwise, there may be
some weird behavior in RM.
