> 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.
