Kai Zheng commented on HADOOP-11542:
------------------------------------
Hi [~zhz], I checked it and am sure what I updated are adding some ByteBuffer
version of functions, and adjusting some formats necessarily, and more
comments. I just uploaded the original version for your reference. I agree it's
good to check the arithmetic logic using tests, that's why I provided quite a
few. When other RS coders like ISA one are coming, I will update the tests so
that the decoding of the encoded data can be done in another coder, which will
make us further ensure about its correctness.

> new codec and coder framework, which could be useful in case native support
> isn't available or convenient in some environments or platforms.
