Yes. Run as many Spark jobs as you want and Spark will queue them given CPU and RAM available for you in the cluster. > job execution is blocking i.e. a new job can not be initiated until the > previous one commits. That's how usually people code their apps. The more advanced approach is to use SparkContext from multiple threads and execute actions (that will submit jobs). > What does it mean that : "Spark’s scheduler is fully thread-safe" You can use a single SparkContext from multiple threads.
