Aaron T. Myers commented on HDFS-2978:
--------------------------------------

bq. Also, ignoring the above comment, would it be a good idea to have this available in 1.x
too?

Sure, good thinking. I'd be happy to provide such a patch.

Todd/Hitesh - does Suresh's reply re: why JSON for JMX data address your concerns?
