             Summary: Improve logging for when master cannot connect to slaves
                 Key: MESOS-1826
                 URL: https://issues.apache.org/jira/browse/MESOS-1826
             Project: Mesos
          Issue Type: Improvement
    Affects Versions: 0.20.0
            Reporter: Thomas Rampelberg
            Priority: Minor


When first setting a mesos cluster up, it is possible to get into a state where your slaves are constantly re-registering. This happens because the slave pid is not reachable from the master.

Currently, the master logs make it pretty tough to figure out that this is the problem that is occurring. It would be fantastic if there was a better explanation in the logs, something like:

    Unable to connect to slave X at x.x.x.x:5051. Please make sure that host is reachable from your master.
