Mayank Bansal updated MAPREDUCE-3026:
-------------------------------------
Release Note: (was: There are two changes which needs to be done in order
to fix the Null Pointer Exception.
1. Job tracker was not setting the job statuses for the leaf queues, so we need
to fix the job tracker to set the running job statuses for the leaf queues.
2. When we are decserializing the jobqueueInfo object at the client side then
it was actually expecting the jobqueueInfo object however from the Queinfo
class we were passing the Queinfo object which needs to be changed to
jobqueueInfo object.)
