Vinod Kumar Vavilapalli commented on YARN-2986:
-----------------------------------------------

Agreed, we should avoid all those cases. In theory, none of the tests (outside 
of those that test scheduler internal functionality) should depend on 
scheduler-type. This is in line with the expectation that I as an app developer 
shouldn't need to write code with conditionals on scheduler-type.

> Support hierarchical and unified scheduler configuration
