> NameNode's image and edits directories can be separated (HADOOP-3948).
> So the name-node can have 3 types of storage directories. 
> And each directory should contain only those files that correspond to its type:
> # combined image and edits directory: should contain {{fsimage}} and {{edits}}
> # image only directory should contain only {{fsimage}}
> # edits only directory should contain only {{edits}}
