> 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will be notified that the StorageDirectory is no longer valid.
