Thomas Graves updated SPARK-28577:
----------------------------------
    Docs Text: On YARN, The off heap memory size is now separately included for 
the user in the container size it requests from YARN. Previously you had to add 
that into the overhead memory you requested, that is no longer needed.

> Ensure executorMemoryHead requested value not less than MEMORY_OFFHEAP_SIZE 
> when MEMORY_OFFHEAP_ENABLED is true
