Subject Re: Forcibly Move A Topic

If all replicas of a partition are offline, your partition is unavailable.
As such, there isn't a way for Kafka to copy data consistently from brokers
that are offline. If you are worried that an entire rack or data center
might go offline, you will need to ensure that your replicas are not on the
same rack or you have a multi dc strategy using cross dc replicas or mirror
makers. We have a JIRA open to do rack aware replica assignment
automatically, but the work is not complete yet.
