Hi there!
I am working with Hadoop 2.0.3-alpha on Centos 6.4, using Eclipse Juno.

Just beginning the elephant book 3rd edition, came across a sample of IOUtils.copyBytes, IOUtils.closeStream

I do not have these commands at IOUtils. what am I missing here? in order to work with hadoop objects inside eclipse, which external jars and from which library do I need to import?

Many thanks in advance to all those who answer!
