> 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()
?
