MR AM can change to SUCCESS state but crash and fail to write JobHistory ------------------------------------------------------------------------
Key: MAPREDUCE-3559 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3559 Project: Hadoop Map/Reduce Issue Type: Bug Components: mr-am, mrv2 Affects Versions: 0.23.0 Reporter: Vinod Kumar Vavilapalli In such corner cases, clients can see that the job has become successful but they cannot get any information from JobHistoryServer. And there is no means of figuring out what happened in the system except from the AM logs. Ideally we should set the JobState to become SUCCESS as the last step, once everything else is done. The code changes may be a bit complicated to achieve this, but we can investigate and see. -- This message is automatically generated by JIRA.
