      Description

      It would be helpful if there were a way to query the namenode to verify that it is basically healthy. In particular, that all the expected threads are running, data structures appear sane, etc. Administrators could use this interface to verify that the namenode is both up and essentially functional, attaching cron jobs, notification, etc. as required.
