--------------------------------------

             Summary: NoSuchElementException in ReplicaManager
                 Key: KAFKA-6949
                 URL: https://issues.apache.org/jira/browse/KAFKA-6949
             Project: Kafka
          Issue Type: Bug
            Reporter: Jason Gustafson


I found this in a failed execution of 
kafka.admin.ReassignPartitionsClusterTest.shouldExpandCluster. Looks like we're missing some option checking.
