[jira] [Created] (SPARK-9336) Remove all extra JoinedRows

Reynold Xin created SPARK-9336:
----------------------------------

             Summary: Remove all extra JoinedRows
                 Key: SPARK-9336
                 URL: https://issues.apache.org/jira/browse/SPARK-9336
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Reynold Xin
            Assignee: Reynold Xin


They were added to improve performance (so JIT can inline the JoinedRow calls). However, we can also just improve it by projecting output out to UnsafeRow in Tungsten variant of the operators.
