### Background When changing some coordinator's conf and then restart, coordinator will accept client `getAssignment` request immediately, but it will serve for jobs request based on the partial registered shuffle-servers, which will make some jobs gotten not enough required shuffle-servers and then slow the running speed. I think we should make coordinator wait for more than one shuffle-server heartbeat interval before serving for client. During out-of-service, requests from client will fallback to slave coordinator. Besides, I think this rejection mechanism could be enabled by the coordinator conf. -- This is an automated message from the Apache Git Service.
