> Similar with HDFS-4757, we need to update the inodeMap after node replacement. Because a lot of node replacement happens in the snapshot branch (e.g., INodeDirectory => INodeDirectoryWithSnapshot, INodeDirectory <=> INodeDirectorySnapshottable, INodeFile => INodeFileWithSnapshot ...), this becomes a non-trivial issue.
