Description

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:

1. combined image and edits directory: should contain fsimage and edits
2. image only directory should contain only fsimage
3. edits only directory should contain only edits
