> I use SimpleDateFormat to Parse the JobHistory File before

>  public static String getJobDetail(JobInfo job) {
>         StringBuffer jobDetails = new StringBuffer("");

>        return jobDetails.toString();
> }
> {code}
> But I find I query the SubmitTime and LaunchTime in hive and compare JobHistory File
time , I find that the submitTime  and launchTime was wrong.
> Finally,I change to use the FastDateFormat to parse the time format and the time become
right
