rgw: "cluster [WRN] bad locator @X on object @X...." in cluster log
During the clean up phase of teuthology (run as master as the --ceph-suite), an egrep of the logs reveals warnings similar to:
"cluster [WRN] bad locator @9 on object @9 op osd_op(client.4146.0:79 9.5 9:b08b92bd::::head [delete] snapc 0= ondisk+write+known_if_redirected e30) v8"
This does not happen on runs with kraken.

- Project changed from Ceph to rgw
- Subject changed from "cluster [WRN] bad locator @X on object @X...." in cluster log to rgw: "cluster [WRN] bad locator @X on object @X...." in cluster log
- Priority changed from Normal to High
seems like a problem where we send a delete with an empty object name. Maybe on radosgw-admin user rm, but not 100% sure yet.

Yeah, I managed to track this down in one of my runs: http://qa-proxy.ceph.com/teuthology/cbodley-2017-03-01_14:55:21-rgw-wip-rgw-encryption---basic-mira/871984/teuthology.log

which leads to:

If the user's email address is empty, we try to remove an object with an empty name.

- Status changed from New to Need Review
- Backport set to jewel kraken
The teuthology failures don't occur on kraken or earlier, but I still tagged for backport to be safe. It's possible that whatever osd changes that led to the 'bad locator' warnings may be backported as well.
