Date Fri, 08 Dec 2017 02:53:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-18191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16282951#comment-16282951

Rui Li commented on HIVE-18191:
-------------------------------

Does the comment need to be updated with the change?
{code}
-      if (row instanceof VectorizedRowBatch) {
+      if (vectorized) {
         // We need to check with 'instanceof' instead of just checking
         // vectorized because the row can be a VectorizedRowBatch when
         // FetchOptimizer kicks in even if the operator pipeline is not
{code}
