Got it, so the command should be spark-submit -class com.hadoopexam.MyTask -master yarn --deploy-mode cluster SSPARK HOME/lib/hadoopexam.jar 10.

And we should specify the jar file path as SSPARK HOME/lib/hadoopexam.jar.

Yes, that's necessary to launch the driver on one of the cluster nodes.

Should we also include --deploy-mode cluster in the command?

Yes, that makes sense. It specifies the main class of the application.

I think I should use -class com.hadoopexam.MyTask in the spark-submit command.

Hmm, I'm still a bit unsure. Maybe we should double-check the Spark documentation to be sure?

Good point. I think the 'deploy-mode cluster' option is only necessary if you want to explicitly specify that the driver should run on a cluster node, rather than on your local machine.

But wait, doesn't the 'spark-submit' command automatically launch the driver on a cluster node by default? Do we really need the 'deploy-mode cluster' part?

Yeah, I agree. The 'deploy-mode cluster' option will ensure the driver runs on a cluster node, which is what the question is asking for.

Okay, let's think this through. The question says we want to launch the driver on one of the cluster nodes, so the 'deploy-mode cluster' option seems like the right choice.

Hmm, this question seems straightforward enough, but I'm a bit unsure about the 'deploy-mode' part. Does that mean the driver will run on a cluster node or on my local machine?
