>          Components: YARN Client
>    Affects Versions: 0.10.0
>            Reporter: Ufuk Celebi

> Currently, the number of vcores per YARN container is set to 1.
> It is desirable to allow configuring this value. As a simple heuristic it 
> makes sense to at least set it to the number of slots per container.
