---------------------------------------

             Summary: In-Memory relation has a bad default size.
                 Key: SPARK-3235
                 URL: https://issues.apache.org/jira/browse/SPARK-3235
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Michael Armbrust
            Assignee: Michael Armbrust
            Priority: Blocker


All operators must have a default size that prevents automatic broadcasting 
otherwise we can easily OOM the driver.
