Alejandro Abdelnur commented on YARN-689:
-----------------------------------------
[~acmurthy], thanks for looking into this. What is for concern for decoupling
minimum and increment and exposing it the API? We can keep, minimum to be the
increment if minimum is not specified, then we preserve by default the current
behavior. Also, the patch already contains the work for the 3 schedulers (fifo,
capacity and fair). The changes are trivial, and again, with default values
nothing would change.

> Currently we overloading the minimum resource value as the actual multiplier
> used by the scheduler.
> Today with a minimum memory set to 1GB, requests for 1.5GB are always
> translated to allocation of 2GB.
> We should decouple the minimum allocation from the multiplier.
> The multiplier should also be exposed to the client via the
> RegisterApplicationMasterResponse
