There may be some misunderstanding of how DoY works. The only info that
users can pass to DoY is that which is in the DoY config file. We should add
arguments to that file which will be passed through the DoY client to the DoY
AM, and from there, as an env var, to the Drillbit containers. We already do
this for memory so that both Drill and YARN agree on memory. We should do the
same for CPU so that Drill, YARN and cgroups agree on the number of CPUs that
Drill can use.
Since this feature is MapR-only, it might be OK to require that users alter
their `drill-env.sh` to set an environment variable the forces Drill to police
itself under YARN.
