----------------------------------
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
Affects Versions: 3.0.0-alpha2
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: 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
