What if the executor process down with its docker container still alive? As I tested, I killed an executor process in one of my mesos slave machines, the process detail just like:
root 17166 9569 0 Mar22 ? 00:01:39 mesos-docker-executor --container=mesos-0d58cb85-e726-479a-a57a-83405e3ae580-S3.b995031b-9c46-4713-9050-518aa306c6aa --docker=docker --docker_socket=/var/run/docker.sock --help=false --mapped_directory=/mnt/mesos/sandbox --sandbox_directory=/data/mesos/slaves/0d58cb85-e726-479a-a57a-83405e3ae580-S3/frameworks/5cfc9845-05c0-45b1-acc0-595ab92075d2-0000/executors/archtools_hearthstone.eless_eless.uwsgi.353f920b-eff6-11e5-97d3-aeb4726ea116/runs/b995031b-9c46-4713-9050-518aa306c6aa --stop_timeout=0ns The I checked the container with name "mesos-0d58cb85-e726-479a-a57a-83405e3ae580-S3.b995031b-9c46-4713-9050-518aa306c6aa" was still alive. My mesos version is 0.25.0. And the mesos slave machine kernel version is Linux 3.10.0-229.11.1.el7.x86_64. I mean if executor process crashed/killed for whatever reasons(but the container is alive), a new container will launch for the task_lost event. So a container created by the dead executor process would be undiscoverable to my framework. I want to know if I am wrong, or there is a way to handle this scenario. I hope my question is clear, if not, please let me know. Any feedback would be appreciated. [😊]
