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

bq. @Aaron, the current patch should be fine as all the data currently exposed follows the same json serialize approach. However, at some point, it would be good to look at exactly how this is being used or meant to be used and fix the mbean output if needed.

Sure, makes sense. Want to file a JIRA for that?
