How to kill a running Spark application?

I have a running Spark application where it occupies all the cores where my other applications won't be allocated any resource.

I did some quick research and people suggested using YARN kill or /bin/spark-class to kill the command. However, I am using CDH version and /bin/spark-class doesn't even exist at all, YARN kill application doesn't work either.

Can anyone with me with this?

Solution

copy paste the application Id from the spark scheduler, for instance application_1428487296152_25597
connect to the server that have launch the job
yarn application -kill application_1428487296152_25597
