How MySQL Group Replication get primary node ip address

According to MYSQL 5.7 Reference Manual :

• http://dev.mysql.com/doc/refman/5.7/en/group-replication-find-primary.html

• http://dev.mysql.com/doc/refman/5.7/en/group-replication-monitoring.html

We can use the sql below to find the primary-node's hostname when group replication is deployed in single-mode :

mysql> SELECT * FROM performance_schema.replication_group_members WHERE MEMBER_ID = (SELECT VARIABLE_VALUE FROM performance_schema.global_status WHERE VARIABLE_NAME= 'group_replication_primary_member');
+---------------------------+--------------------------------------+-------------+-------------+--------------+
| CHANNEL_NAME              | MEMBER_ID                            | MEMBER_HOST | MEMBER_PORT | MEMBER_STATE |
+---------------------------+--------------------------------------+-------------+-------------+--------------+
| group_replication_applier | 9176f4d3-c7f6-11e6-bcf7-fa163ee40410 | myhost      |       24801 | ONLINE       |
