[jira] [Resolved] (HDFS-9696) Garbage snapshot records lingering forever

     [ https://issues.apache.org/jira/browse/HDFS-9696?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yongjun Zhang resolved HDFS-9696.
---------------------------------
    Resolution: Duplicate

Hi [~kihwal],

Thanks a lot for reporting the issue here. Upon investigation, we think it's likely duplicate of HDFS-9406, which is now resolved. I'm closing this jira for now. If you still see the problem after applying the fix HDFS-9406, please feel free to reopen.

Thanks.

> 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.
