> The docker_container_executor_session.sh is generated like below:
> {code}
> ### get the pid of docker container by "docker inspect"
> echo `/usr/bin/docker inspect --format {{.State.Pid}} container_1438681002528_0001_01_000002`
> .../container_1438681002528_0001_01_000002.pid.tmp
> ### rename *.pid.tmp to *.pid
> /bin/mv -f .../container_    1438681002528_0001_01_000002.pid.tmp .../container_1438681002528_0001_01_000002.pid
> ### launch the docker container
> /usr/bin/docker run  --rm  --net=host --name container_1438681002528_0001_01_000002 -v
... library/mysql /container_1438681002528_0001_01_000002/launch_container.sh" 
> {code}
> This is obviously wrong because you can not get the pid of a docker container before
starting it.  When NodeManager try to kill the container, pid zero is always read from the
pid file.
