Haven't seen the part 2. I think this was complete.

Neo: No.
Morpheus: Why Not?
Neo: Because I don't like the idea that I'm not in control of my life.

Subject: LZO compression for Map output in Hadoop 0.20+?

   New to Hadoop (now using 0.20.1), I want to know how to choose and set up 
compression methods for Map output, especially how to configure and use LZO 
compression?

  Specifically, please share your experience for the following 2 scenarios. 
Thanks!

   (1) Is there a global setting in some hadoop configuration files for naming 
a compression method (e.g. LZO) such that it will be used to compress Map 
output by default? and how?

   (2) How to use a compression method (e.g. LZO) in java code (I noticed that 
in javadoc, org.apache.hadoop.mapred is labeld Deprecated)?

Thanks!
