> 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}
