Hi all, I was trying to test --supervise flag of spark-submit.
The documentation [1] says that, the flag helps in restarting your application automatically if it exited with non-zero exit code. I am looking for some clarification on that documentation. In this context, does application means the driver? Will the driver be re-launched if an exception is thrown by the application? I tested this scenario and the driver is not re-launched. ~/spark-1.6.1/bin/spark-submit --deploy-mode cluster --master spark://10.29.83.162:6066 --class org.apache.spark.examples.ExceptionHandlingTest /home/spark/spark-1.6.1/lib/spark-examples-1.6.1-hadoop2.6.0.jar I killed the driver java process using 'kill -9' command and the driver is re-launched. Is this the only scenario were driver will be re-launched? Is there a way to simulate non-zero exit code and test the use of --supervise flag?
