> FSImage currently derives from Storage and FSEditLog has to call methods directly on FSImage to access the filesystem. This JIRA is to separate the Storage class out into NNStorage so that FSEditLog is less dependent on FSImage. From this point, the other parts of the circular dependency should be easy to fix.
