[jira] [Commented] (HBASE-8712) archivedHFileCleaner seems to be racing and complains about missing files

    [ https://issues.apache.org/jira/browse/HBASE-8712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13678566#comment-13678566 ] 

Matteo Bertozzi commented on HBASE-8712:
----------------------------------------

This is not a race or a bug... is just that FSUtils.listStatus() is too verbose if the directory doesn't exists... 
In this case is the HFileLinkCleaner (enabled with snapshot) that tries to look for cloned tables by looking inside the .link-xyz directory... and there're no cloned tables (and no .link-xyz directory)... so you get the DEBUG log...

> Testing 0.95.1 RC1, I found that just inserting data and splitting seems to trigger a bug in the archivedHFileCleaner that makes it complain about missing files. It seems to happen mostly to reference files post-split.
> I'm attaching a grep I did with the file name (you'll see the same file name happens to be in 2 regions, it's because it's a reference file).
