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

             Summary: In place filtering in Not Filter doesn't handle nulls correctly.
                 Key: HIVE-4575
                 URL: https://issues.apache.org/jira/browse/HIVE-4575
             Project: Hive
          Issue Type: Sub-task
            Reporter: Jitendra Nath Pandey
            Assignee: Jitendra Nath Pandey


 The FilterNotExpr evaluates the child expression and takes the compliment of the selected
vector. Since child expression filters out null values, the compliment includes the nulls
in the output. This is incorrect because not(null) = null.
