>                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1105
>             Project: Bookkeeper
>          Issue Type: Bug
>          Components: bookkeeper-client, bookkeeper-server
>    Affects Versions: 4.5.0
>            Reporter: Andrey Yegorov
>            Assignee: Andrey Yegorov
>            Priority: Critical
> Ran into this issue:
> due to some misconfiguration of new node and rack assignments we've ended up 
> with nodes being assigned to default rack. We are not using region-aware, 
> only rack-aware policy.
> This generates the following sequence of events:
> - default rack is /default-region/default-rack even though region-aware is 
> not used.
> - other nodes mapped to racks like /rack1, /rack2 etc.
> - mixing /region/rack and /rack styles is not allowed, but exception on 
> addition of such nodes is swallowed. All following nodes to add (if there 
> were any) just skipped as result.
