      Description

      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.
