Examples of INodeDirectoryWithSnapshot

org.apache.hadoop.hdfs.server.namenode.snapshot.INodeDirectoryWithSnapshot
The directory with snapshots. It maintains a list of snapshot diffs for storing snapshot data. When there are modifications to the directory, the old data is stored in the latest snapshot, if there is any.
