> If I execute simple command like date on docker container, the application
> failed to complete successfully.
> for example,
> {code}
> $ yarn jar
> $HADOOP_HOME/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-2.7.1.jar
> -shell_env YARN_CONTAINER_RUNTIME_TYPE=docker -shell_env
> YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=hadoop-docker -shell_command "date" -jar

> 17/04/12 00:16:40 INFO distributedshell.Client: Application did finished
> unsuccessfully. YarnState=FINISHED, DSFinalStatus=FAILED. Breaking monitoring
> loop
> 17/04/12 00:16:40 ERROR distributedshell.Client: Application failed to
> complete successfully
> {code}
> The error log is like below.
> {code}
> ...
> Failed to write pid to file
> /cgroup_parent/cpu/hadoop-yarn/container_xxxx/tasks - No such process
> ...
> {code}
> When writing pid to cgroup tasks, container-executor doesn’t check docker
> container’s status.
> If the container finished very quickly, we can’t write pid to cgroup tasks,
> and it is not problem.
> So container-executor needs to check docker container’s exit code during
> writing pid to cgroup tasks.
