    Description

      Currently ErasureCodingWorker gets recovery related info and performs the erasure decoding task using the raw erasure coder API. In this follow-on issue, the recovery relate info can be further mapped to construct BlockGroup object to utilize and call the higher level ErasureCoder API.
