> Currently the FSImage class is responsible both for storage management (eg 
> moving around files, tracking file names, the VERSION file, etc) as well as 
> for the actual serialization and deserialization of the "fsimage" file within 
> the storage directory.
> I'd like to refactor the loading and saving code into new classes. This will 
> make testing easier and also make the major changes in HDFS-1073 easier to 
> understand.
