      Description

      When running history viewer in local mode (specifying file:///<path/to/hodlogs> as path to logs), it throws IndexOutOfBoundsException due to the following code:

            String[] jobDetails = 
                JobInfo.decodeJobHistoryFileName(jobFiles[0].getName()).split("_");
            trackerHostName = jobDetails[0];
            trackerStartTime = jobDetails[1];
      

      The reason is because there are some directories under the log directories that do not conform to the log file naming convention, and the length of the jobDetails array is 1.

      History viewer should be more defensive and ignore (possibly with warning) files or directories that it does not recognize.
