Hello All,
I second this question. I have a MS SQL "rank" function which I would
like to run, the results it gives appears to suggest it is executed Mapper
side as opposed to reducer side, even when run with "cluster by"
constraints.

Hi,
What's the lifecycle of a hive udf. If I call
select MyUDF(field1,field2) from table;
Then MyUDF is instantiated once per mapper, and within each mapper
execute(field1, field2) is called for each reducer? I hope this is the case,
but I can't find anything about this in the documentation
