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

             Summary: JobHistoryServer has no information about applications if the MR-AM crashes
                 Key: MAPREDUCE-5418
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5418
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobhistoryserver, mr-am
    Affects Versions: 2.0.5-alpha
            Reporter: Karthik Kambatla
            Priority: Critical


Currently, the AM writes the job-specific information to HDFS only after it finishes; the JHS needs this info to display anything. If the AM fails, this info is not written and the JHS fails to display anything for that job.
