[jira] [Created] (SPARK-3600) RandomRDDs doesn't create primitive typed RDDs

Xiangrui Meng created SPARK-3600:
------------------------------------

             Summary: RandomRDDs doesn't create primitive typed RDDs
                 Key: SPARK-3600
                 URL: https://issues.apache.org/jira/browse/SPARK-3600
             Project: Spark
          Issue Type: Bug
          Components: MLlib
    Affects Versions: 1.1.0
            Reporter: Xiangrui Meng
            Assignee: Xiangrui Meng


RandomDataGenerator doesn't have a classTag or @specilaized. So the generated RDDs are RDDs of objects, that cause huge storage overhead.
