I filed issues HDFS-7636 for the sorting. > Track and display failed DataNode storage locations in NameNode. > ---------------------------------------------------------------- > > Key: HDFS-7604 > URL: https://issues.apache.org/jira/browse/HDFS-7604 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode, namenode > Reporter: Chris Nauroth > Assignee: Chris Nauroth > Attachments: HDFS-7604-screenshot-1.png, HDFS-7604-screenshot-2.png, HDFS-7604-screenshot-3.png, HDFS-7604.prototype.patch > > > During heartbeats, the DataNode can report a list of its storage locations that have been taken out of service due to failure (such as due to a bad disk or a permissions problem). The NameNode can track these failed storage locations and then report them in JMX and the NameNode web UI. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
