Description

when job complete, there are WARN complains in the log:

2014-03-19 13:31:10,036 WARN org.apache.hadoop.mapreduce.v2.jobhistory.FileNameIndexUtils: Unable to parse launch time from job history file job_1395204058904_0003-1395206473646-root-test_one_word-1395206966214-4-2-SUCCEEDED-root.test-queue-1395206480070.jhist : java.lang.NumberFormatException: For input string: "queue"

because there is in the queue name 'test-queue', we split the job history file name by , and get the ninth item as job start time.
FileNameIndexUtils.java

private static final int JOB_START_TIME_INDEX = 9;

but there is another potential issue:
if I also include '-' in the job name(test_one_world in this case), there are all misunderstand.
