> This is to define the even higher level API *ErasureCodec* to possiblly consider all
the essential aspects for an erasure code, as discussed in in HDFS-7337 in details. Generally,
it will cover the necessary configurations about which *RawErasureCoder* to use for the code
scheme, how to form and layout the BlockGroup, and etc. It will also discuss how an *ErasureCodec*
will be used in both client and DataNode, in all the supported modes related to EC.
