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

bq. numDataUnits probably sounds a little better.
OK, let me wait another chance to update the patch one more time to use it. I 
didn't notice your comment when uploading the revision.

> 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.
