    Fix Version/s:     (was: 2.8.0)

> DockerLinuxContainer can't limit the cpu usage

>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: nodemanager

>  Remaining Estimate: 240h
> When I use DockerLinuxContainer, I found that the function of limiting cpu usage doesn't
make effect. Because DockerLinuxContainer regard the exitCode of  "docker inpsect" as pid.
But When I got this pid, the command of "launch.sh" has started, then we can't add the child
process or threads into the cgroup, so the restrictions of cpu usage doesn't make effect。
