Gilbert Song created MESOS-9868:
-----------------------------------

             Summary: NetworkInfo from the agent /state endpoint is not correct.
                 Key: MESOS-9868
                 URL: https://issues.apache.org/jira/browse/MESOS-9868
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 1.8.0
            Reporter: Gilbert Song


NetworkInfo from the agent /state endpoint is not correct, which is also different from the networkInfo of /containers endpoint. Some frameworks rely on the state endpoint to get the ip address for other containers to run.

]
}

The ip addresses are different^^.

The container is in RUNNING state and is running correctly. Just the state endpoint is not correct. One thing to notice is that the state endpoint used to show the correct IP. After there was an agent restart and master leader re-election, the IP address in the state endpoint was changed.

Here is the checkpoint CNI network information
