Description:
Hi,

In Bug#89194, I describe a situation breaking Group Replication.  One of the lines in the error logs is the following:

2018-01-01T19:30:20.976766Z 86 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'FIRST' position 65

The “START SLAVE” in this message is wrong.  This should read “START GROUP_REPLICATION”.

Many thanks for looking into that,

JFG

How to repeat:
See Bug#89194.

Suggested fix:
Fix the error message not to refer to standard replication but to Group Replication.
