---------------------------------

Thanks ATM and Harsh for creating this issue and clarifying. This sounds to be an interesting
feature, and I would love to work on it.

> Presently `hdfs dfsadmin -saveNamespace' will attempt to save a snapshot of the file
system metadata state into all configured storage dirs. It would be nice if we could optionally
specify an arbitrary local dir on the NN to save the FS state into, instead of the configured
storage dirs.
