--------------------------------------
Summary: SummarizedJob class should be
Key: MAPREDUCE-6096
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6096
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: jobhistoryserver
Affects Versions: trunk
Reporter: zhangyubiao
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() ?
