> I use SimpleDateFormat to Parse the JobHistory File before
> private static final SimpleDateFormat dateFormat =
> new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
> public static String getJobDetail(JobInfo job) {
> StringBuffer jobDetails = new StringBuffer("");
> SummarizedJob ts = new SummarizedJob(job);
> jobDetails.append(job.getJobId().toString().trim()).append("\t");
> jobDetails.append(job.getUsername()).append("\t");
> jobDetails.append(job.getJobname().replaceAll("\\n",
> "")).append("\t");
> jobDetails.append(job.getJobQueueName()).append("\t");
> jobDetails.append(job.getPriority()).append("\t");
> jobDetails.append(job.getJobConfPath()).append("\t");
> jobDetails.append(job.getUberized()).append("\t");
>
> jobDetails.append(dateFormat.format(job.getSubmitTime())).append("\t");
>
> jobDetails.append(dateFormat.format(job.getLaunchTime())).append("\t");
>
> jobDetails.append(dateFormat.format(job.getFinishTime())).append("\t");
> return jobDetails.toString();
> }
> 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 chang to use the FastDateFormat to parse the time format and the
> time become right
