Hong Zhiguo updated YARN-4016:
------------------------------
Description:
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.
