Ashutosh Chauhan commented on HIVE-2597: ---------------------------------------- +1 > Repeated key in GROUP BY is erroneously displayed when using DISTINCT > --------------------------------------------------------------------- > > Key: HIVE-2597 > URL: https://issues.apache.org/jira/browse/HIVE-2597 > Project: Hive > Issue Type: Bug > Reporter: Alex Rovner > Assignee: Navis > Attachments: HIVE-2597.3.patch.txt, HIVE-2597.4.patch.txt, > HIVE-2597.D8967.1.patch, HIVE-2597.D8967.2.patch > > > The following query was simplified for illustration purposes. > This works correctly: > {code:sql} > select client_tid, "" as myvalue1, "" as myvalue2 from clients cluster by > client_tid > {code} > The intent here is to produce two empty columns in between data. > The following query does not work: > {code:sql} > select distinct client_tid, "" as myvalue1, "" as myvalue2 from clients > cluster by client_tid > {code} > {noformat} > FAILED: Error in semantic analysis: Line 1:44 Repeated key in GROUP BY "" > {noformat} > The key is not repeated since the aliases were given. Seems like Hive is > ignoring the aliases when the "distinct" keyword is specified. -- This message was sent by Atlassian JIRA (v6.2#6252)
