Shane Kumpf commented on YARN-7667:
-----------------------------------
Thanks for the patch, [~ebadger]. Overall this looks good. I tested a few
different values and can see the correct grace period being set in the cmd file
and in the stop call in the docker daemon debug logs:
{code:java}
Apr 07 15:05:44 host dockerd[8987]: time="2018-04-07T15:05:44.577115114Z"

Couple minor comments on the patch:
# Is there a reason not to set the value for
{{yarn.nodemanager.runtime.linux.docker.stop.grace-period}} in
{{yarn-default.xml}} to 10?
# I don't think the new {{DockerStopCommand}} constructor is necessary, {{new
DockerStopCommand(containerId).setGracePeriod(dockerStopGracePeriod)}} would
achieve the same.
> Docker Stop grace period should be configurable

> {{DockerStopCommand}} has a {{setGracePeriod}} method, but it is never
