Hi, Please consider the following scenario.
I've started the spark master by invoking the org.apache.spark.deploy.master.Master.startSystemAndActor method in a java code and connected a worker to it using the org.apache.spark.deploy.worker.Worker.startSystemAndActor method. and then I have successfully created a java spark & SQL contexts and performed SQL queries. My question is, can I change this order? Can I start the master first, then create a spark context... and later on connect a worker to the master? While trying out this scenario, I have successfully started the master. Please see the screenshot here. But when I create an spark context, it terminates automatically. is it because the master not being connected to a worker? cheers -- Niranda
