    }
    if (!this.cliClientService.connect(leaderId.getEndpoint())) {
        return new Status(-1, "Fail to init channel to leader %s", leaderId);
    }
    TransferLeaderRequest rb = cliOptions.getRaftMessagesFactory().transferLeaderRequest().groupId(groupId).leaderId(leaderId.toString()).peerId(peer.isEmpty() ? null : peer.toString()).build();
    try {
        final Message result = this.cliClientService.transferLeader(leaderId.getEndpoint(), rb, null).get();
        return statusFromResponse(result);
    } catch (final Exception e) {
        return new Status(-1, e.getMessage());
    }
