> Some UDF should take all columns starting from second or third one and in
> this case, star argument(HIVE-3490) cannot be used. It's not pleasant to
> specify all of them especially when the table has many of columns. For
> example,
> {noformat}
> select some_udtf(a2,a3,a4,a5,a6) as (a2,a3,a4,a5,a6) from table;
> {noformat}
> it can be simplified to
> {noformat}
> select some_udtf(a2...) as (a2,a3,a4,a5,a6) from table;
> {noformat}
> if HIVE-2608 would be committed, it can be simplified further
> {noformat}
> select some_udtf(a2...) from table;
> {noformat}
