Description

When setting up a compression codec in an MR job the full class name of the codec must be used.

To ease usability, compression codecs should be resolved by their codec name (ie 'gzip', 'deflate', 'zlib', 'bzip2') instead their full codec class name.

Besides easy of use for Hadoop users who would use the codec alias instead the full codec class name, it could simplify how HBase resolves loads the codecs.
