[jira] [Created] (MAPREDUCE-6075) HistoryServerFileSystemStateStore can create zero-length files

Jason Lowe created MAPREDUCE-6075:
-------------------------------------

             Summary: HistoryServerFileSystemStateStore can create zero-length files
                 Key: MAPREDUCE-6075
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6075
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobhistoryserver
    Affects Versions: 2.3.0
            Reporter: Jason Lowe
            Assignee: Jason Lowe


When the history server state store writes a token file it uses IOUtils.cleanup() to close the file which will silently ignore errors.  This can lead to empty token files in the state store.
