[jira] [Created] (SPARK-9415) MapType should not support equality & ordering

Reynold Xin created SPARK-9415:
----------------------------------

             Summary: MapType should not support equality & ordering
                 Key: SPARK-9415
                 URL: https://issues.apache.org/jira/browse/SPARK-9415
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Reynold Xin
            Priority: Blocker


MapType today happened to support equality comparison because we use Scala maps under the hood. However, map type should not support equality, hash, or ordering (i.e. cannot be used as join keys, grouping keys, or in equality/ordering tests).

We should throw the appropriate analysis exception for these cases.
