             Summary: fsck, dfsadmin -report, and NN WebUI should report number of blocks that have 1 replica
                 Key: HDFS-13658
                 URL: https://issues.apache.org/jira/browse/HDFS-13658
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
    Affects Versions: 3.1.0
            Reporter: Kitti Nanasi
            Assignee: Kitti Nanasi


fsck, dfsadmin -report, and NN WebUI should report number of blocks that have 1 replica. We have had many cases opened in which a customer has lost a disk or a DN losing files/blocks due to the fact that they had blocks with only 1 replica. We need to make the customer better aware of this situation and that they should take action.
