Subject [jira] [Commented] (HIVE-11623) CBO: Calcite Operator To Hive Operator (Calcite Return Path): fix the tableAlias for ReduceSink operator
Date Tue, 25 Aug 2015 17:18:46 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14711647#comment-14711647
] 

Jesus Camacho Rodriguez commented on HIVE-11623:
------------------------------------------------

[~pxiong], when is the table alias null vs equal to the empty string? Is there a general rule?
If we have columns with null table aliases and empty table aliases, is this a valid setting?

Thanks
