Kai Zheng commented on HDFS-7353:
---------------------------------

Updated the patch. Change summary:
1. Let it focus on the API and basic part, moving out of any concrete coder to make it simple.

> This is to abstract and define raw erasure coder API across different codes algorithms
like RS, XOR and etc. Such API can be implemented by utilizing various library support, such
as Intel ISA library and Jerasure library.
