      Description

      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.
