    Description

      As discussed in HADOOP-11847, due to and inherited from the limitation of HDFS-RAID codes, RSErasureDecoder has to compute and recover unnecessarily some units even they're not really erased, but just not to read.
      This is to resolve the limiation and improve RSErasureDecoder for better performance.
