----------------------------------------
Konstantin Shvachko commented:
> We should not place them into removeDir, but rather re-read configuration
> at this moment. This would also help if a new directory was configured
> as a new storage.
If we go this route - we should probably only allow addition of the new (or
restoration of the failed) directories. No removal of existing/working ones.
> Try to restore failed replicas of Name Node storage (at checkpoint time)
