Description

partitionReplicaAssignment currently stores the list of assigned replicas as a sequence. When a broker comes online, the replica state machine adds the broker to the list of assigned replicas. It should do that only if the replica is already not in the list of assigned replicas. This causes the replication factor to be incorrectly calculated
