Subject [jira] Updated: (HADOOP-6349) Implement FastLZCodec for fastlz/lzo algorithm
Date Tue, 20 Jul 2010 01:20:59 GMT

Eli Collins updated HADOOP-6349:
--------------------------------

    Attachment: hadoop-6349-1.patch

Patch attached, this was as far as I got before getting distracted.
* Re-based on trunk. Cleans up carriage returns and indenting, removes most gratuitous uses
of "this"
* Fixes some bugs in TestCodecPerformance.java
* Got JFastLZCompressor working, at least for the seeds that were breaking (the finished method
was incorrect)
* Made some progress on JFastLZDecompressor but found a seed (see the one used in TestCodecPerformance)
that causes a checksum missmatch and getRemaining needs to be implemented.
