Kai Zheng commented on HDFS-7353:
---------------------------------
Hi [~szetszwo],
Thanks for your thorough and great review.
bq. ec also can mean error correcting...
Could we discuss the naming in the overall master JIRA HDFS-7285. When we have
a decision, we need to ensure it's consistent in all the places, not just in
this part.
bq. Should the package be moved under hdfs?
Let's discuss this in HDFS-7337, the 'master' JIRA of this. Raw erasure coder
is a part of the codec framework.
bq. By "The number of elements", do you mean "length in bytes"? Should it be
long instead of int?
Sorry for the confusion. I need to update the obsolete comment. It's not
"length in bytes", but regarding how many stripping units. A unit can be a
byte, a chunk or buffer and even a block.
For other comments, I will surely get them resolved and provide new patch. Good
catches!

> 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.
