> 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.
