        Patch looks reasonable to me. A couple of nits:

        1. The import removal looks unrelated. Let us leave it in.
        2. getLimitIfAny doesn't really say much about what the method does. Rename it to a more descriptive name?

        Until we have container resizing, I don't think we should allow requesting 0 vcores or 0 mb.

        Its a good discussion to have whether we should allow zero vcores. I think its ok if jobs do not care about getting any CPU allocated to them and just use whatever leftover CPU there exists.
        Irrespective I think we should not be crashing in the AM when calculating available containers. If we need to enforce it I agree job submission is a better way to rejecting those values.

        The patch itself looks good. Thanks Anubhav Dhoot
        But I was wondering if we should allow tasks with 0 vcores (Maybe within the context of reservation definition, where in 1 or more resource requests can have 0 vcores). Will it make sense to validate this at job submission time the value of mapreduce.map.cpu.vcores / mapreduce.reduce.cpu.vcores as well ?
