---------------------------------
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.
> Add a parameter to `hdfs dfsadmin -saveNamespace' to allow an arbitrary
> storage dir

> Key: HDFS-2746
> URL: https://issues.apache.org/jira/browse/HDFS-2746
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: namenode
> Affects Versions: 2.0.0-alpha
> Reporter: Aaron T. Myers
>
> 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.
