    • The output of hdfs fsck now also contains information about decommissioning replicas.

    Description

      Fsck doesn't count replicas that are on decommissioning nodes. If a block has all replicas on the decommissioning nodes, it will be marked as missing, which is alarming for the admins, although the system will replicate them before nodes are decommissioned.
      Fsck output should also show decommissioning replicas along with the live replicas.
