-----------------------------------
Summary: Improve recovering Docker containers when slave is
contained
Key: MESOS-2115
URL: https://issues.apache.org/jira/browse/MESOS-2115
Project: Mesos
Issue Type: Improvement
Reporter: Timothy Chen
Currently when docker containerizer is recovering it checks the checkpointed
executor pids to recover which containers are still running, and remove the
rest of the containers from docker ps that isn't recognized.
This is problematic when the slave itself was in a docker container, as when
the slave container dies all the forked processes are removed as well, so the
checkpointed executor pids are no longer valid.
We have to assume the docker containers might be still running even though the
checkpointed executor pids are not.
