Sreekanth Ramakrishnan commented on HADOOP-4445:
------------------------------------------------
The information disparity comes in because, when a task is scheduled to be
executed the Capacity Scheduler increases the number of the tasks running in a
queue and then it passes the actual list of the tasks to the task tracker. So
there is a disparity between what is actually running and what is scheduled to
run on the task tracker.
So I think we should be changing the _Number of Running <task>_ to represent
_Running <task> Scheduled_ and _<Task> To be scheduled_.
Would that make sense to the end user?
> Wrong number of running map/reduce tasks are displayed in queue information.
