We should capture this and explain to the user that the issue is that the dns isn't resolving and to check the host being used please.

Similar note - there is a issue with external zookeeper ip not getting resolved and scheduler getting killed without any errors

That could hang for a bit on retries, makes sense. So maybe 2-3 things. We
should log more, will add that to the metrics issue. Thanks!
