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!
