RE: Logging level
Hmm, it doesn't seem possible before MAPREDUCE-336 is fixed.

Yes, I need a way to change the logging level of map/reduce tasks for the jobs of my Hive query, without affecting the logging level of other jobs or Hadoop daemons. How do I set hadoop.root.logger to do that?

You need to set hadoop looging level to debug if you are looking at
map task logs. I guess hadoop.root.logger is your friend.
