Yes the cluster was to a degree restarted in a rolling fashion but due to
some other events causing the brokers to be rather confused the ISR for a
number of partitions became empty and a new controller was elected.
KAFKA-1647 sounds exactly like the problem I encountered. Thank you.

Bryan,
Did you take down some brokers in your cluster while hitting KAFKA-1028? If
yes, you may be hitting KAFKA-1647 also.
