Subject [jira] [Created] (YARN-4016) docker container is still running when app is killed
Date Tue, 04 Aug 2015 09:50:04 GMT
Hong Zhiguo created YARN-4016:
---------------------------------

             Summary: docker container is still running when app is killed
                 Key: YARN-4016
                 URL: https://issues.apache.org/jira/browse/YARN-4016
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Hong Zhiguo
            Assignee: Hong Zhiguo


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.
