---------------------------------
Thanks, junping for the review.
bq. Why we must need node address if app is not finished? Can we ask RM to get
the nodeAddress instead?
So, currently, we could only get the running container report from RM, and get
the finished container report from ATS. It would go to this else-if clause when:
1. the application is running
2. the container is finished
3. this container is not the AM Container, and we only send AM Container
metrics to ATS.
This is a good catch. This makes people confuse.
{code}
+ System.out.println("Please specify the nodeAddress, and use "
+ + "yarn logs -applicationId <appId> -containerId <containerId> "
+ + "--nodeAddress <nodeAddress> to get the container logs");
{code}
Have modified the print out message, and make it more clear to users.
> More improvement to get Container logs without specify nodeId
