SparkEnv

Related Docs: object SparkEnv | package spark

class SparkEnv extends Logging

:: DeveloperApi :: Holds all the runtime environment objects for a running Spark instance (either master or worker), including the serializer, Akka actor system, block manager, map output tracker, etc. Currently Spark code finds the SparkEnv through a global variable, so all the threads can access the same SparkEnv. It can be accessed by SparkEnv.get (e.g. after creating a SparkContext).

NOTE: This is not intended for external use. This is exposed for Shark and may be made private in a future release.
