Jing Zhao commented on HDFS-4611:
---------------------------------
The current patch looks good. Only one question: while loading the fsimage,
when a referred inode (i.e., the inode that has been renamed in history) is
loaded, some of the snapshots associated with its diffs may not have been
loaded from the fsimage yet, since snapshots are loaded while we load the
corresponding INodeDirectorySnapshottable. Maybe we need to load all the
snapshots (by going through all the snapshottable directories) in the very
beginning without setting the root's parent, and revisit these snapshots when
we load the corresponding snapshottable directories?
