Galera SST fails

I am using MariaDB 10.2

I have node2 (2.2.2.2) running as a slave to some external database.
I bootstrapped node2 as the first member of a Galera cluster "my_cluster"

When I try to join node1 (1.1.1.1) to the cluster I get failures.

I see 4 rsync processes running on node1:

mysql    20458  0.0  0.0   4504   788 ?        S    10:49   0:00 sh -c wsrep_sst_rsync --role 'joiner' --address '1.1.1.1:4444' --datadir '/var/mysql/datadir/'   --parent '20440' --binlog '/var/mysql/log/mysql-bin'

and on node2:

```

wsrep_sst_donor=2.2.2.2

wsrep_sst_donor should have the node name, not the IP address.

A similar case was reported in the MariaDB Jira as MDEV-13687.
