> Currently the "hdfs getconf" tool can only print out certain keys, like the list of NNs, etc. It would be handy to allow it to fetch an arbitrary configuration. For example, users may wish to write shell scripts that interact with their hadoop cluster, and it is useful to be able to fetch configs like the name of the superuser, or the state of whether HA is enabled.
