Tom White commented on HADOOP-7323:
-----------------------------------
This looks good. The only nit I noticed is that the javadoc on codecsByName in
CompressionCodecFactory is incorrect.
> Add capability to resolve compression codec based on codec name

> 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.
