             Summary: Filter below Sort causes exception
                 Key: DRILL-380
                 URL: https://issues.apache.org/jira/browse/DRILL-380
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Aman Sinha


Here's a plan that contains a Filter below Sort.  The stack trace for the 
exception is shown further below.  Having a SelectionVectorRemover between the 
Filter and Sort eliminates the problem but should not be required.
