Hi all,
I met an issue that docker container doesn't be killed in the process of upgrading. I upgrade mesos from 0.21.0 to 0.25.0, when upgrading a slave, on which a marathon task running (UI would see this). I expect that the task should be killed and another same marathon task should be started in other slaves. but the task didn't be killed. If run `docker ps` in all the slaves, would find that there 4 docker container are running that task in the same cluster, but I only started one. Does someone meet this issue? Thanks, Best regards, Chen, Qiang
