------------------------------------------------------------
I think it is broken by HDFS-10763 and a real bug. I will fix it soon. It is
not an issue for trunk to branch-2.8, as the lease is inode ID based.

> We have a cluster where the snapshot feature might have been tested years
> ago. When the HDFS does not have any snapshot, but I see filediff records
> persisted in its fsimage. Since it has been restarted many times and
> checkpointed over 100 times since then, it must haven been persisted and
> carried over since then.
