>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 1.0.0

> In yarn environment, let's say :
> MaxAM = Maximum allocatable memory
> ExecMem - Executor's memory
> if (MaxAM > ExecMem && ( MaxAM - ExecMem) > 384m ))
>   then Maximum resource validation fails w.r.t executor memory , and application master gets launched, but when resource is allocated and again validated, they are returned and application appears to be hanged.
> Typical use case is to ask for executor memory = maximum allowed memory as per yarn config
