> 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.
