[jira] [Created] (SPARK-3762) clear all SparkEnv references after stop

Davies Liu created SPARK-3762:
---------------------------------

             Summary: clear all SparkEnv references after stop
                 Key: SPARK-3762
                 URL: https://issues.apache.org/jira/browse/SPARK-3762
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: Davies Liu
            Priority: Critical


SparkEnv is cached in ThreadLocal object, so after stop and create a new SparkContext, old SparkEnv is still used by some threads, it will trigger many problems.

We should clear all the references after stop a SparkEnv.
