SparkEnv

class SparkEnv extends Logging

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 thread-local variable, so each thread that accesses these objects needs to have the right SparkEnv set. You can get the current environment with SparkEnv.get (e.g. after creating a SparkContext) and set it with SparkEnv.set.
