Before BUG#28796, an empty host was used to identify that an instance was no longer a slave. However, BUG#28796 changed this behavior and one cannot set an empty host. Besides, a RESET SLAVE only cleans up information on the next event to retrieve from the master, disables ssl and resets heartbeat period. So a call to SHOW SLAVE STATUS after issuing a RESET SLAVE still returns some valid information, such as host, port, user and password. To fix this problem, we have introduced the command RESET SLAVE ALL that does what a regular RESET SLAVE does and also clears host, port, user and password information thus allowing users to identify when an instance is no longer a slave.
