    Description

      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.
