>
> In HADOOP-11646, {{ErasureCoder}} API is defined to support encoding/decoding
> of a block group considering the most simple but often case that only one
> coding step is involved. This is to enhance the API to support complex cases
> requiring multiple steps for encoding/decoding of a block group.
> Recovering parity blocks will be supported here also, because it involves at
> least two steps: step 1. recover data blocks first; step2. call encoder to
> compute the erased parity blocks with all the ready data blocks.
