org.apache.hadoop.hdfs.server.namenode.snapshot.SnapshotManager
Manage snapshottable directories and their snapshots. This class includes operations that create, access, modify snapshots and/or snapshot-related data. In general, the locking structure of snapshot operations is:
1. Lock the {@link FSNamesystem} lock in {@link FSNamesystem} before callinginto {@link SnapshotManager} methods.
2. Lock the {@link FSDirectory} lock for the {@link SnapshotManager} methodsif necessary.
