Hemanth Yamijala commented on HADOOP-5214:
------------------------------------------

There are no tests in this patch, because it is essentially fixing a threading 
synchronization issue that is hard to write unit tests for. The existing 
FairShare scheduler tests make sure that everything is still functional.
