Alejandro Abdelnur updated HADOOP-7323:
---------------------------------------
Attachment: HADOOP-7323b.patch
Thanks Tom.
I've updated the Javadocs.
I've also improved the alias resolution to resolve to the short class name,
both with 'codec' ending and without 'codec' ending.
This means that the aliases for GzipCodec are 'gzip' and 'gzipcodec' (both case
insensitive)
> 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.
