Description

Need fix bugs:
1) args of queue CLI is without "queue" even if you run with "yarn queue -status ..", the args is ["-status", "..."]. The assumption is incorrect.
2) It is possible that there's no related QueueInfo with specified queue name, and null will be returned from YarnClient, so NPE will raise. Added a check for it, and will print proper message
3) When failed to get QueueInfo, should return non-zero exit code.
4) Add tests for above.
