Chris Nauroth updated HDFS-7604:
--------------------------------
Attachment: HDFS-7604.002.patch
I'm attaching patch v002. I've also attached screenshots 5-7 showing what it
looks like in the web UI now.
It's still very similar to the change summary I gave in one of my prior
comments. The differences are:
* The UI now uses a separate page to track nodes with volume failures. The
existing DataNode information page is unchanged. On the Datanode Volume
Failures page, you'll see only nodes that currently have volume failures, and
the details.
* The internal tracking and the heartbeat protocol now uses a
{{VolumeFailureSummary}} message. This tracks more detailed information than
the prior version, which was just a list of strings.
> Track and display failed DataNode storage locations in NameNode.

> 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.
