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

             Summary: Regression: Forcing a merge join instead of a hash join results in a
Failure while reading vector.  Expected vector class of org.apache.drill.exec.vector.BigIntVector
but was holding vector class org.apache.drill.exec.vector.VarBinaryVector.
                 Key: DRILL-928
                 URL: https://issues.apache.org/jira/browse/DRILL-928
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
            Reporter: Ramana Inukonda Nagaraj
            Priority: Critical


Test case:

alter session set `planner.enable_hashjoin` = false;
select count(*)
  from supplier s, lineitem l, orders o
        where s.s_suppkey = l.l_suppkey
                and o.o_orderkey = l.l_orderkey
        and l.l_shipdate between date '1995-01-01' and date '1995-12-31' ;

If the alter session is removed the query works fine. Which leads me to believe its something
in either the mergejoin or the sort before the mergejoin step.
