> 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 $HADOOP_HOME/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-2.7.1.jar
-num_containers 1 -timeout 3600000
> …
> 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.
