This will be `spark.executor.cores` instead (which is currently not already
documented). The description would be something like:
"""
Default: 2 in YARN mode, all the available cores on the worker in
standalone mode.
The number of cores to use on each executor. For YARN and standalone mode
only.
In standalone mode, setting this parameter allows an application to run
multiple executors on the same worker, provided that there are enough cores on
that worker. Otherwise, only one executor per application will run on each
worker.
