Owen O'Malley commented on HADOOP-3858:
---------------------------------------

We should also increase the number fetched at once to 500, like the TaskTracker.

> JobClient doesn't wait for all task completion events before exiting

> The JobClient should pull all of the task completion events from the 
> JobTracker before exiting the loop and returning to the application. 
> Otherwise the failing task may be lost in the backlog since only 10 task 
> events are fetched per a second.
