> @felixcheung I am not sure that our users are so interested in getting a
list of cores per executors and calculate total numbers cores by summurizing
the list. It will just complicate API and implementation, from my point of view.
A list of cores per executors can be useful, one scenario is users may want
to know how many slots are available, and that requires sum all the slots on
each executors, with # of slots = # of cores on an executor / CPUS_PER_TASK
