Ming Ma created HDFS-6745:
-----------------------------

             Summary: Display the list of "very-under-replicated blocks" as well as the files
on NN webUI
                 Key: HDFS-6745
                 URL: https://issues.apache.org/jira/browse/HDFS-6745
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Ming Ma


Sometimes admins want to know the list of "very-under-replicated blocks" before major actions
such as decommission; as these blocks are more likely to turn into missing blocks. "very-under-replicated
blocks"  are those blocks with live replica count of 1 and replicator factor of >= 3.
