------------------------------------
Hi [~zhz],
Thanks for your helpful review to move a little bit faster.
bq.I don't think we need to put Java in the class name
I want to distinguish it from native coders. We'll also have ISA one for RS
code scheme. How about {{JRSRawEncoder}} ? Note as it's in pure Java its
efficiency is very low so I thought it would be good not to have users think
it's the default and right good RS implementation.
bq.I think we should remove "test usage". They'll be used all-around if native
coders are not available.
OK, agree.
Regarding {{GaloisField}} and related, it's almost the same from HDFS-RAID. I
did add some functions to support ByteBuffer. As you suggested, I will compare
and give comments for the updated parts.
Will update the patch when HADOOP-11541 is in.
