> When I Parse the JobHistory in the HistoryFile,I use the Hadoop System's
> map-reduce-client-core project
> org.apache.hadoop.mapreduce.jobhistory.JobHistoryParser class and
> HistoryViewer$SummarizedJob to Parse the JobHistoryFile(Just Like
> job_1408862281971_489761-1410883171851_XXX.jhist)
> and it throw an Exception Just Like
> Exception in thread "pool-1-thread-1" java.lang.NullPointerException
> at
> org.apache.hadoop.mapreduce.jobhistory.HistoryViewer$SummarizedJob.<init>(HistoryViewer.java:626)
> at
> com.jd.hadoop.log.parse.ParseLogService.getJobDetail(ParseLogService.java:70)
> After I'm see the SummarizedJob class I find that attempt.getTaskStatus() is
> NULL ， So I change the order of
> attempt.getTaskStatus().equals (TaskStatus.State.FAILED.toString()) to
> TaskStatus.State.FAILED.toString().equals(attempt.getTaskStatus())
> and it works well .
> So I wonder If we can change all attempt.getTaskStatus() after
> TaskStatus.State.XXX.toString() ?
