> Currently we used the parity units + data units order for the inputs,
> erasedIndexes and outputs parameters in the decode call in raw erasure coder,
> which inherited from HDFS-RAID due to impact enforced by {{GaliosField}}. As
> [~zhz] pointed and [~hitliuyi] felt, we'd better change the order to make it
> natural for HDFS usage, where usually data blocks are before parity blocks in
> a group. Doing this would avoid some reordering tricky logic.
