Package org.apache.spark

Class SparkEnv

Object
org.apache.spark.SparkEnv
All Implemented Interfaces:
org.apache.spark.internal.Logging
public class SparkEnv extends Object implements org.apache.spark.internal.Logging
:: DeveloperApi :: Holds all the runtime environment objects for a running Spark instance (either master or worker), including the serializer, RpcEnv, 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).
