Kai Zheng updated HADOOP-11646:
-------------------------------
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. (was: 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 HDFS-7353 to perform
concrete encoding or decoding.)
