[jira] Created: (HADOOP-6389) Add support for LZF compression

Add support for LZF compression
-------------------------------

                 Key: HADOOP-6389
                 URL: https://issues.apache.org/jira/browse/HADOOP-6389
             Project: Hadoop Common
          Issue Type: New Feature
          Components: io
            Reporter: Tatu Saloranta


(note: related to [HADOOP-4874])

As per Doug's earlier comments, LZF does indeed look like a good compressor candidate for fast compression/decompression, good enough compression rate.
>From my testing it seems at least twice as fast at compression, and somewhat faster for decompressing than gzip.
Code from [http://h2database.googlecode.com/svn/trunk/h2/src/main/org/h2/compress/] is applicable, and I have tested it with json data.

I hope to have more to spend on this in near future, but if someone else gets to this first that'd be good too.
