Tsz Wo (Nicholas), SZE commented on HDFS-4244:
----------------------------------------------
- update SafeModeException message for FSNamesystem.deleteSnapshot
- use getMutableINodesInPath for SnapshotManager.deleteSnapshot.
- why removing checkPathLength(..) in NameNodeRpcServer.createSnapshot?
- combine SnapshotManager.deleteDiffsForSnapshot(..) to
INodeDirectorySnapshottable.removeSnapshot(..). Note that
INodeDirectorySnapshottable is extending INodeDirectoryWithSnapshot.
In the meantime, let me change TestINodeDirectoryWithSnapshot to test
deleteSnapshotDiff.
> Support deleting snapshots
