        Added as RN 2.0.1:

        If you try to add a node during cluster rebalance, the
        rebalance may fail and return the messages <literal>{detected_nodes_change</literal>
        or <literal>{ns_node_disco_events</literal>. To avoid this error complete your
        cluster rebalance, add the new node and then rebalance once again. This issue will
        be fixed in future releases.
