 *         Do not join node that has no distributed metastorage if feature is supported in current topology and
 *         distributed metastorage has already been used ({@link #getUpdatesCount()} is not zero).

 *         to apply it to the cluster.
 *     </li>
 *     <li>
 *         Do not join node if its distributed metastorage version hash differs from the local one. In such cases
 *         node is probably from different cluster or has some inconsistent data.
