> This is to define ErasureCoder API for encoding and decoding of BlockGroup.
> Given a BlockGroup, ErasureCoder extracts data chunks from the blocks and
> leverages RawErasureCoder defined in HADOOP-11514 to perform concrete
> encoding or decoding. Note this mainly focuses on the basic fundamental
> aspects, and solves encoding, data blocks recovering and etc. Regarding
> parity blocks recovering, as it involves multiple steps, HADOOP-11550 will
> handle it.
