                nodesMatchingRequirements; unsatisfiedRequirements; bootstrapRequirements);

            if (nodesMatchingRequirements.contains(transportService.getLocalNode()) == false) {
                logger.info("skipping cluster bootstrapping as local node does not match bootstrap requirements: {}";
                    bootstrapRequirements);
                bootstrappingPermitted.set(false);
