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
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)
