Reid Chan commented on HBASE-20404: ----------------------------------- bq. Are they exceptions. Are they 'problems'? Both, no. bq. I as an operator can actually do something about? Yes, you can delete yourself, but no need, since it is a chore. bq. Should they be LOG.warn? DEBUG or remove if you like, either does no harms. > Ugly cleanerchore complaint that dir is not empty > ------------------------------------------------- > > Key: HBASE-20404 > URL: https://issues.apache.org/jira/browse/HBASE-20404 > Project: HBase > Issue Type: Bug > Affects Versions: 2.0.0 > Reporter: stack > Priority: Major > > I see these big dirty exceptions in my master log during a long-run....
