             Summary: Integrate Chocolate Cloud RS coder implementation
                 Key: HDFS-11503
                 URL: https://issues.apache.org/jira/browse/HDFS-11503
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: erasure-coding

            Reporter: Andrew Wang
            Assignee: Marcell Feher

Quote from Marcell on HDFS-7285:

First of all let me introduce ourselves: we are Chocolate Cloud from Denmark, we use erasure
coding to improve storage solutions. We already have Reed-Solomon and Random Linear Network
Coding backends for Liberasurecode, and now we are at the final stage of developing our RS
plugin to HDFS-EC. The performance of our plugin is similar to ISA-L's, in some configurations
we are better, in others we are worse (our initial speed comparison charts can be found here:

We would like our plugin to become officially supported in Hadoop 3.0. We can already provide
a preliminary version of our (native) library and a patch with the necessary glue code for
the next alpha release.

I'd like to know your thoughts about whether it's possible and how it could be achieved.

P.S: I'm happy to share more details if there's interest
