Kai Zheng commented on HADOOP-11798:
------------------------------------
To make it easy for the native part, I would start with this simpler one. It
will help prepare for some basic setups for complex ones, like based on ISA-L.
> Native raw erasure coder in XOR codes

> Key: HADOOP-11798
> URL: https://issues.apache.org/jira/browse/HADOOP-11798
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: io
> Reporter: Kai Zheng
> Assignee: Kai Zheng
> Fix For: HDFS-7285
>
>
> Raw XOR coder is utilized in Reed-Solomon erasure coder in an optimization to
> recover only one erased block which is in most often case. It can also be
> used in HitchHiker coder. Therefore a native implementation of it would be
> deserved for performance gain.
