-----------------------------
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.
