> If the NameNode or JournalNode aborts due to an unexpected error in the 
> metadata directories, often the root cause is that the metadata files are in 
> an unexpected state, or permissions are broken on the directories.  This 
> issue proposes that during abort, we write additional information about the 
> directory state and permissions to the logs.  This can help speed up 
> diagnosis, and ultimately recovery.
