Arvind Prabhakar updated HIVE-1459:
-----------------------------------
Assignee: (was: Arvind Prabhakar)
> wildcards in UDF/UDAF should expand to all columns (rather than no columns)
> ---------------------------------------------------------------------------
>
> Key: HIVE-1459
> URL: https://issues.apache.org/jira/browse/HIVE-1459
> Project: Hive
> Issue Type: Bug
> Components: UDF
> Affects Versions: 0.6.0
> Reporter: John Sichi
>
> When a function is invoked with a wildcard * for its parameter, it should be
> passed all of the columns in the expansion, exception in the special case of
> COUNT, where none of the columns should be passed.
> As part of this issue, we also need to test qualified wildcards (e.g. t.*)
> and Hive's extension for regular-expression selection of column subsets.
