    Description

      org.apache.hadoop.mapreduce.v2.hs.TestJobHistoryParsing can fail because of race condition.

      testHistoryParsingWithParseErrors(org.apache.hadoop.mapreduce.v2.hs.TestJobHistoryParsing)  Time elapsed: 4.102 sec  <<< ERROR!
      java.io.IOException: Unable to initialize History Viewer
              at org.apache.hadoop.fs.RawLocalFileSystem.getFileStatus(RawLocalFileSystem.java:520)
              at org.apache.hadoop.fs.FilterFileSystem.getFileStatus(FilterFileSystem.java:398)

              at org.apache.hadoop.mapreduce.v2.hs.TestJobHistoryParsing.testHistoryParsingWithParseErrors(TestJobHistoryParsing.java:125)
      

      In the checkHistoryParsing() function, after

      HistoryFileInfo fileInfo = jobHistory.getJobFileInfo(jobId);
      

      a thread named MoveIntermediateToDone will be launched to move history file from done_intermediate to done directory.
      If the history file is moved,

            HistoryViewer viewer = new HistoryViewer(fc.makeQualified(
                fileInfo.getHistoryFile()).toString(), conf, true);
      

      will throw IOException´╝îbecause the history file is not found.
