 Description   

Users can see the following error message in MariaDB:

2019-07-23 23:24:06 1337162 [ERROR] Error reading packet from server: A slave with the same server_uuid/server_id as this slave has connected to the master; the first event 'mysql-bin.000645' at 83358751, the last event read from 'mysql-bin.000645' at 83360832, the last byte read from 'mysql-bin.000645' at 83360859. (server_errno=4052)

This error message should not mention server_uuid, because server_uuid does not exist in MariaDB. The server_uuid system variable is available starting in MySQL 5.6, but we chose not to port it to MariaDB. See MDEV-5277 for more information.
