> Project: Hadoop HDFS
> Issue Type: Bug
> Components: snapshots
> Affects Versions: 3.0.0

> Snapshot.Root, though is a subclass of INodeDirectory, is only used to
> indicate the root of a snapshot. In the meanwhile,
> AbstractINodeDiff#snapshotINode is used as copies recording the original
> state of an INode. Thus we should not put them into INodeMap.
> Currently when loading FSImage we did not check the type of inode and wrongly
> put these two types of nodes into INodeMap. This may replace the nodes that
> should stay in INodeMap.
