Scott Chen updated MAPREDUCE-1970:
----------------------------------
Attachment: MAPREDUCE-1970.txt
The patch is a Reed-Solomon erasure code implementation.
Since the parity size are very small (4-5) in our use case, I don't think we
need some fancy algorithms.
A gaussian elimination for solving the error values will be just enough.
