> {code}
> public void encode(ByteBuffer[] inputs, ByteBuffer[] outputs);
> {code}
> Currently when we do encode, the outputs are all parity blocks, we should be
> able to encode part of parity blocks.
> This is required when we do datanode striped block recovery, if one or more
> parity blocks are missed, we need to do encode to recovery them. Only encode
> part of parity blocks should be more efficient than all.
