>                 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.
