Varun Saxena commented on YARN-6428:
------------------------------------

You are right about changing it to double will be a far reaching change i.e. it 
will impact quite a few areas. All our queue capacities for instance are stored 
as float.
To be honest there are inconsistencies in usage of double and float all across.
So adding a float version of method will be the easiest fix.
However, let Wangda comment on this.
