[jira] [Commented] (HIVE-12272) CBO: Calcite Operator To Hive Operator (Calcite Return Path) : columnPruner prunes everything when union is the last operator before FS

    [ https://issues.apache.org/jira/browse/HIVE-12272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14977504#comment-14977504 ] 

Ashutosh Chauhan commented on HIVE-12272:
-----------------------------------------

Change makes sense. However, [~pxiong] do you know why this is an issue only for operator return path and not ast return path?
