[jira] [Created] (SPARK-1708) Add ClassTag parameter on accumulator and broadcast methods

Matei Zaharia created SPARK-1708:
------------------------------------

             Summary: Add ClassTag parameter on accumulator and broadcast methods
                 Key: SPARK-1708
                 URL: https://issues.apache.org/jira/browse/SPARK-1708
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
            Reporter: Matei Zaharia
            Priority: Blocker
             Fix For: 1.0.0


ClassTags will be needed by some serializers, such as a Scala Pickling based one, to come up with efficient serialization. We need to add them on Broadcast and probably also Accumulator and Accumulable. Since we're freezing the public API in 1.0 we have to do this before the release.
