If you are running it as java program, then you need to take care of all these setups which would become tricky. And I guess even now you are facing the issue due to incorrect jars in classpath.</P><P>Also please help me understand the usecase ? Whats the purpose of launching spark job using yarn rest api ?</P><P>If you do simple spark-submit, it will take care of negotiating resources from YARN and to run the application.</P> Wed, 20 Jun 2018 12:33:19 GMT ssharma 2018-06-20T12:33:19Z
