Cannot avoid disabling relay_log_purge #84

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Switch back and forth between two servers
2. relay_log_purge will be set to OFF on both

I think this is expected and by design, but I want to be able to avoid setting 
relay_log_purge to OFF. Our use case only involves a Master and a Standby. The 
reason for using MHA is to have tooling performing the failover/switchover and 
avoid human error etc. We do not rely on being able to read relays from other 
slaves (since we do not have them). Because of this, we do not want to 
introduce new components for handling relay-log rotation etc. We want to use 
the built in purge.

I cannot find a way to have MHA avoid disabling relay_log_purge, is this 
possible?
