      Description

      MAPREDUCE-777 breaks jobtracker UI for hierarchial queues. When jobtracker.jsp is accessed, it throws the following exception:

      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)
              .... 
      

      (Issue number and the line number in code match - 1007. Some fun for a Hadoop developer )
