[jira] Commented: (HIVE-840) no error if user specifies multiple columns of same name as output

    [ https://issues.apache.org/jira/browse/HIVE-840?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12771562#action_12771562 ] 

He Yongqiang commented on HIVE-840:
-----------------------------------

Thanks, Namit. 
You mean the error message ""column alias " + name + " already exists."  We need a parameter 'name' in the error message, so it may not fit in ErrorMsg.
