Description
Note1: I'm not a big believer in NM->OS replication, but I think it's not good that it doesn't start at all, and moreover it floods the error log rather than produce a clear fatal error and give up.
Note2: I've set the guilty version to 10.0.2 as i assume it's something to fix on master rather than on old slave; please adjust if it's wrong.
I start 5.5 server with
--server-id=1 --port=3306 --log-slave-updates --log-bin
|
and 10.0 server with
--server-id=2 --port=3307 --log-slave-updates --log-bin
|
then I execute on 5.5 server
MariaDB [test]> change master to master_port=3307, master_host='127.0.0.1', master_user='root'; |
Query OK, 0 rows affected (0.74 sec) |
 |
MariaDB [test]> start slave;
|
Query OK, 0 rows affected (0.01 sec) |
Slave status shows everything is okay (it's on the current trees built from source; on 5.5.30 release build + 10.0.2 release builds I saw IO thread staying in 'Connecting' state):

But note how the relay logs rotates in a rapid fashion, while the master log position remains the same:
