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
Affects Versions: 0.7.1
Reporter: Alex Rovner
The following query was simplified for illustration purposes.
This works correctly:
select client_tid, "" as myvalue1, "" as myvalue2 from clients cluster by
client_tid
The intent here is to produce two empty columns in between data.
The following query does not work:
select distinct client_tid, "" as myvalue1, "" as myvalue2 from clients cluster
by client_tid
FAILED: Error in semantic analysis: Line 1:44 Repeated key in GROUP BY ""
The key is not repeated since the aliases were given. Seems like Hive is
ignoring the aliases when the "distinct" keyword is specified.
