Kai Zheng commented on HDFS-7338:
---------------------------------
Thanks for your clarifying. We would leverage existing native libraries
implementing the code. I have checked the ISA-L library, which supports
encoding and decoding using either Cauchy matrix or Classic Vandermonde matrix.
For decoding, since in most time only one parity block is to be recovered, one
optimization would be to simply use XOR.
