I tried submitting the application like this with 2 cores as you can see with the [2].
/opt/cloudera/parcels/CDH-5.2.1-1.cdh5.2.10.12/lib/spark/bin/spark-submit --class SimpleApp --master spark://10.0.1.230:7077[2] --jars $(echo /home/ec2-user/sparkApps/SimpleApp/lib/*.jar | tr ' ' ',') /home/ec2-user/sparkApps/SimpleApp/target/simple-project-1.0.jar So I checked the url of the master (10.0.1.230). I found the results interesting... Workers: 2 Cores: 4 Total, 0 Used //so does this mean running it on the localhost has 0 cores? Also when I ran my application, it did not show under "Running Applications". Also, under "Completed Applications" none of my previous runs were recorded (all were from spark-shell). I tried changing my submit script to 10.0.1.231:70877[2], but that did not change anything. Any suggestions on if I should change my submit script or how I could do so? Thanks a lot for the help!
