Kai Zheng updated HDFS-8020:
----------------------------
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.
(was: As a task of HDFS-7348, to process *stripping* coding commands from
NameNode or other scheduler services/tools, we need to first be able to restore
BlockGroup and schema information in DataNode, which will be used to construct
and perform coding work using {{ErasureCoder}} API.)
