Damien Carol updated HIVE-2597:
-------------------------------
Description:
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.
