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. So I'd like to have some run-time configuration of my UDF: I'm curious how people do this. Is there a way I can send it a value or have it access a file, etc? How about performing a query against the hive store? Thanks, Ranjan
