Jing Zhao updated HDFS-4760:
----------------------------

    Attachment: HDFS-4760.005.patch

Yes. setReferredINode is called by replaceSelf and replaceChild. The previous patch missed
a scenario in replaceChild. Update the patch to fix.

> 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.
