Can slider stop/start instance on a specific node

Hi,guys.
I’m new to Slider world and use slider to deploy koya(kafka).
I wonder can I stop or start a KAFKA_BROKER on a specific node. Since there may be some problems with the host, I have to stop the broker on that host, but not on all hosts. And current stop/start command will stop/start all brokers.
How can I achieve that, if not, will future version support this feature.

Thanks,
Chengeng ou

Yes, it will right away (if there is sufficient resource in the cluster).
If it is a production Slider Kafka app you are running, try bringing up a
new test app and try it out on it. This will ensure no other YARN
configuration is going to result in killing the production app.

Thanks. 
After slider kill container, will it attempt to restart a container before reaches slider.yarn.restart.limit?

    Would killing the container for that specific broker be an acceptable

Would killing the container for that specific broker be an acceptable
solution?
