[jira] [Created] (SPARK-11675) Remove shuffle hash joins

Reynold Xin created SPARK-11675:
-----------------------------------

             Summary: Remove shuffle hash joins
                 Key: SPARK-11675
                 URL: https://issues.apache.org/jira/browse/SPARK-11675
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Reynold Xin
            Assignee: Reynold Xin


They are off by default. I think we should just standardize on sort merge join for large joins for now, and create better implementations of hash joins if needed in the future.
