-----------------------------------
(btw, your patch seems to be bad -- lots of unrelated changes)
> Remove references to StorageDirectory from JournalManager interface

> The JournalManager interface introduced by HDFS-1799 has a
> getStorageDirectory method which is out of place in a generic interface. This
> JIRA removed that call by refactoring the error handling for FSEditLog. Each
> EditLogFileOutputStream is now a NNStorageListener and listens for error on
> it's containing StorageDirectory. If an error occurs from FSImage, the stream
> will be aborted. If the error occurs in FSEditLog, the stream will be aborted
> and NNStorage will be notified that the StorageDirectory is no longer valid.
