-------------------------------------

             Summary: Block should be marked as *missing* if the all the replicas are on *Decommissioned* nodes.
                 Key: HDFS-10495
                 URL: https://issues.apache.org/jira/browse/HDFS-10495
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.8.0
            Reporter: Rushabh S Shah
            Assignee: Rushabh S Shah


As discussed on HDFS-8872, we should mark a block as missing if all the replicas on decommissioned nodes since we can take the decommissioned nodes out of rotation anytime.
We have seen multiple cases where all the replicas land on decommissioned nodes.
After HDFS-7933, it doesn't mark as missing.
