Could you explain the usage of https://jaceklaskowski.gitbooks.io/mastering-apache-spark/content/spark-MemoryManager.html off heap memory better.

For me http://stackoverflow.com/questions/43330902/spark-off-heap-memory-config-and-tungsten it is unclear if off heap is enabled automatically now (2.1.0) as tungsten is enabled by default.
