@cheddar @himanshug so I think this failure might actually be a problem with the code where the announcer will not always clean up curator paths correctly when it is shutdown. I haven't bug into why this is the case though.

reopening as #2213 doesn't have a fix but hopes to provide more information when it fails.

failed here: https://travis-ci.org/druid-io/druid/builds/103912940, perhaps that provides the more information.
