> > or health checking, because it returns true when the instance is a leader and false otherwise. > > i am confused now. I thought that the HA health-check is supposed to check the status of a leader HS2. If let's say HS2 is running in HA mode and there are 2 HS2 instances, A and B, and A is a leader, then when calling the health check endpoint on A it will return true because A is a leader and when calling the health check endpoint on B it will return false because B is not a leader. If there is a leader failover and B becomes a leader then health checking on A will return false and health check on B will return true. There are several existing tests in `TestActivePassiveHA` that test it. I don't know if in production environments the health checking script always calls the leader HS2 to check the health status or if it might call the slave HS2s. I asked someone who should know more about usage of the health check script, waiting for reply. -- This is an automated message from the Apache Git Service.
