Subject [jira] [Created] (HDFS-9977) CLONE - Erasure coding: DFSInputStream with decode functionality (pread)

dragon created HDFS-9977:
----------------------------

             Summary: CLONE - Erasure coding: DFSInputStream with decode functionality (pread)
                 Key: HDFS-9977
                 URL: https://issues.apache.org/jira/browse/HDFS-9977
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: HDFS-7285
            Reporter: dragon
            Assignee: Zhe Zhang
             Fix For: HDFS-7285


A block group reader will read data from BlockGroup no matter in striping layout or contiguous
layout. The corrupt blocks can be known before reading(told by namenode), or just be found
during reading. The block group reader needs to do decoding work when some blocks are found
corrupt.
