Junping Du commented on YARN-879:
---------------------------------
The history may not show this if tests are commented since YARN-1 (I only check
TestFifoScheduler which belongs to this case). Anyway, we can fix these tests
or remove them completely. It doesn't make sense to me that some test code are
commented for a long time as it just confused people like us. :)

> getResources() will return a list of containers that allocated by RM.
> However, it is now return null directly. The worse thing is: if LOG.debug is
