@dongjoon-hyun I don't see a way to write a test reproducing the issue itself (as there are a lot of timing and concurrency problems involved). Yet, I assume it should be possible to write a test that checks the RPC messages sent from a worker to the master and that worker reregisters only with one master in case of failover and with both masters in case of initial registration. Unfortunately, I didn't find any similar tests checking message exchanges between the worker and the master, so I may need a bit of time to figure it out 🙂 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
