Kai Zheng commented on HADOOP-11920:
------------------------------------
bq. Yes, the caller can pass a direct buffer, but also can use a java heap byte
buffer. Why it should be DirectByteBuffer?
I thought you're right. In that API callers should also certainly use heap
buffers, though native coders prefer direct buffers. Let me update the patch
allowing that with more double check. Thanks!
> Refactor some codes for erasure coders
