Subject [jira] Commented: (HIVE-1015) Java MapReduce wrapper for TRANSFORM/MAP/REDUCE scripts
Date Tue, 05 Jan 2010 06:50:54 GMT


Todd Lipcon commented on HIVE-1015:

Related thought: would be nice to be able to write MAP/REDUCE as straight Java without having
the overhead of streaming and serde. Is there a ticket already for this?
