[jira] [Commented] (HDFS-6745) Display the list of very-under-replicated blocks as well as the files on NN webUI
[ https://issues.apache.org/jira/browse/HDFS-6745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=14170203#comment-14170203 ] Ming Ma commented on HDFS-6745: --- At RPC layer, we can add a new method similar to ClientProtocol.listCorruptFileBlocks. Maybe the new method can take replication threshold as a parameter to retrieve all blocks below that threshold. Then ClientProtocol.listCorruptFileBlocks could become a special case of the new method.

Perhaps people can also specify input parameters such as the definition of very-under-replicated. The count of very-under-replicated blocks will be good for metrics system; how about the full text such as block IDs and file names?
