> Project: Hadoop HDFS
> Issue Type: New Feature

> 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: https://www.chocolate-cloud.cc/Plugins/HDFS-EC/hdfs.html).
> 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
