>                 Key: HADOOP-4482
>                 URL: https://issues.apache.org/jira/browse/HADOOP-4482
>             Project: Hadoop Core
>          Issue Type: Improvement
>          Components: metrics
>    Affects Versions: 0.18.1
>            Reporter: Brian Bockelman
>             Fix For: 0.19.1
>         Attachments: jmx_name.patch
> When Hadoop reports Datanode information to JMX, the bean uses the name "DataNode-" +
storageid.  The storage ID incorporates a random number and is unpredictable.
> This prevents me from monitoring DFS datanodes through Hadoop using the JMX interface;
in order to do that, you must be able to specify the bean name on the command line.
> The fix is simple, patch will be coming momentarily.  However, there was probably a reason
for making the datanodes all unique names which I'm unaware of, so it'd be nice to hear from
the metrics maintainer.
