-----------------------------------
Summary: 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
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.
