             Project: Hadoop Map/Reduce

          Components: mrv2
    Affects Versions: 0.24.0, 0.23.2
            Reporter: Steve Loughran
            Assignee: Steve Loughran
            Priority: Minor
         Attachments: MAPREDUCE-4023.patch

Make the yarn client services more robust against being shut down while not started, or shutdown more than once, by null-checking fields before closing them, setting to null afterwards to prevent double-invocation. This is a subset of MAPREDUCE-3502
