William Kinney updated HADOOP-6349:
-----------------------------------

    Attachment: TestCodecPerformance.java
                testCodecPerfResults.tsv
                HADOOP-6349.patch

Patch contains new files FastLZCodec, JFastLZ, JFastLZCompressor and JFastLZDecompressor.
Also contains a modification to TestCodec, to add FastLZCodec to the test suite. 

JFastLZ is a pure java port of FastLZ.

testCodecPerfResults.tsv is a TSV result from a simple performance test to show the speed
and pack ratio of FastLZ as compared to the other Codecs. TestCodecPerformance.java is the
code which generated the results.
