If true, Spark will attempt to use off-heap memory for certain operations.
If off-heap memory
use is enabled, then <code>spark.memory.offHeap.size</code> must be
positive.

Review comment:
actually this brings up a good question, the size configs say they work for
off heap size for executors, so what cases does this need to apply to the
driver. Is this config really applying to both driver and executors for things
like broadcast blocks, etc.
