             Summary: Master sends messages to the agent before it reregisters
                 Key: MESOS-8062
                 URL: https://issues.apache.org/jira/browse/MESOS-8062
             Project: Mesos
          Issue Type: Bug
            Reporter: Yan Xu
            Priority: Minor


In a few instances the master sends messages to the agent regardless of whether it is active and these messages ends up being dropped by the agent with a warning:

https://github.com/apache/mesos/blob/d79dd983e484bfe5690d34b53716e2c97f1d288e/src/master/master.cpp#L7173

https://github.com/apache/mesos/blob/d79dd983e484bfe5690d34b53716e2c97f1d288e/src/master/master.cpp#L8479

It can happen if the agent restarts but the message arrives before the agent is reregistered. The master could have checked {{Slave.active}} and not send the message. We should prune the warnings from expected cases to reduce the noise in the logs.
