-----------------------------------
I'd like to work on this and will be taking ownership.
> Revisit signalContainer() for docker containers

> Project: Hadoop YARN

> The current signal handling (in the DockerContainerRuntime) needs to be
> revisited for docker containers. For example, container reacquisition on NM
> restart might not work, depending on which user the process in the container
> runs as.
