> MAPREDUCE-777 breaks jobtracker UI for hierarchial queues. When jobtracker.jsp is accessed,
it throws the following exception:
> {code}
> java.lang.NullPointerException
> 	at org.apache.hadoop.mapred.CapacityTaskScheduler.getJobs(CapacityTaskScheduler.java:1007)
> 	at org.apache.hadoop.mapred.JobTracker.getJobsFromQueue(JobTracker.java:3888)
> 	at org.apache.hadoop.mapred.JobTracker.getQueueInfoArray(JobTracker.java:3869)
> 	at org.apache.hadoop.mapred.JobTracker.getRootQueues(JobTracker.java:3830)
> 	at org.apache.hadoop.mapred.jobtracker_jsp.generateSummaryTable(jobtracker_jsp.java:36)
>         .... 
> {code}
> (Issue number and the line number in code match - 1007. Some fun for a Hadoop developer
:) )
