> MR configs rely on YARN configs for certain sizing i.e. map memory and reduce
> memory is dependent on yarn minimum allocation.
> When trying to size MR configs, the minimum limit starts 0.66 GB on a 2 node
> vagrant cluster. There is no clear indication to the user why this min limit
> is setup. Allow the user to progress to YARN first before tweaking MR
> configs would be better.
