Stateful function should be called for all input rows but in if/when
clause, it cannot be guaranteed.
Any reason to declare "protect_column" function to be stateful?

Hi Hive Users:
I have a hive generic hive udf which is called protect_column.
The udf works fine when I call it along.
But when I run the following query:
select case when id = 5 then protect_column(id, 'age', 12L) else id end from
one_row_table ;
It says
Caused by: org.apache.hadoop.hive
