Re: Read namenode data from primary memory
If you're looking to tail the metadata changes for analysis purposes,
there's a more pluggable approach available in 2.x versions.

If you're looking to backup the metadata outside of NameNode, I'd
suggest ditching such an approach and using 2.x's HA HDFS mode
instead.
