Kai Zheng commented on HADOOP-11798:
------------------------------------
The native code looks good overall. One minor is, please clean up the
unnecessary {{#include}} statements in the *.c files.
> Native raw erasure coder in XOR codes

> 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.
