>
> 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.
