Hi Spark users/experts, In Spark source code (Master.scala & Worker.scala), when registering the worker with master, I see the usage of *persistenceEngine*. When we don't specify spark.deploy.recovery mode explicitly, what is the default value used ? This recovery mode is used to persists and restore the application & worker details.
I see when recovery mode not specified explicitly, *BlackHolePersistenceEngine* being used. Am i right ? Thanks, Padma Ch
