---------------------------------
Summary: Remove all unnecessary broadcasts
Key: SPARK-4083
URL: https://issues.apache.org/jira/browse/SPARK-4083
Project: Spark
Issue Type: Improvement
Reporter: Davies Liu
We already broadcast the task (RDD and closure) itself, so some small data used
in RDD or closure do not needed to be broadcasted explicitly any more.
