Alejandro Abdelnur commented on YARN-689:
-----------------------------------------
[~hitesh], if i do this my resource allocation is static, the idea is to
use/leverage YARN resource scheduling/allocation to do it dynamic and maximize
the utilization of resources. In other words, YARN is the only source of truth
for RM, just some resources end up being used out of band. Still their
allocation/tracking is done via YARN.

> 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
