StorageLevel: OffHeap

Jack Kolokasis
Hello everyone,
     I am running a simple word count in Spark and I persist my RDDs
using StorageLevel.OFF_HEAP. While I am running the application, i see
through the Spark Web UI that are persisted in Disk.  Why this happen??
Can anyone tell me how off heap storage Level work ??

Thanks for your help,
