> TaskRunnerLauncherImpl plays a role to launch remote containers via the proxy
> of ContainerManager. This implementation sequentially launches containers, so
> it may take a long time in large clusters. For example, it consumes about 5
> seconds for starting 128 containers in our cluster, consisting of 32 nodes.
> To relieve this time-consuming work, we can make this part parallel by using
> ExecutorService.
