[jira] Updated: (HADOOP-6349) Implement FastLZCodec for fastlz/lzo
algorithm
[ https://issues.apache.org/jira/browse/HADOOP-6349?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
