        throw new IllegalStateException("Cluster is in " + ClusterState.PASSIVE + " state! Operation: " + op);
    }
    // Operation will fail since node is shutting down or cluster is passive.
    if (op.getPartitionId() < 0) {
        throw new HazelcastInstanceNotActiveException("Member " + localAddress + " is currently passive! Operation: " + op);
    }
    // Since operation has a partition id, it must be retried on another node.
    throw new RetryableHazelcastException("Member " + localAddress + " is currently shutting down! Operation: " + op);
}
