Karthik Kambatla commented on MAPREDUCE-5641: --------------------------------------------- Proposal makes sense to me. Do you want to open a YARN JIRA for the YARN-specific changes? > History for failed Application Masters should be made available to the Job > History Server > ----------------------------------------------------------------------------------------- > > Key: MAPREDUCE-5641 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5641 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: applicationmaster, jobhistoryserver > Affects Versions: 2.2.0 > Reporter: Robert Kanter > Assignee: Robert Kanter > > Currently, the JHS has no information about jobs whose AMs have failed. This > is because the History is written by the AM to the intermediate folder just > before finishing, so when it fails for any reason, this information isn't > copied there. However, it is not lost as its in the AM's staging directory. > To make the History available in the JHS, all we need to do is have another > mechanism to move the History from the staging directory to the intermediate > directory. The AM also writes a "Summary" file before exiting normally, > which is also unavailable when the AM fails. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
