Hello! I've read the documentation about the spark architecture, I have the following questions: 1: how many executors can be on a single worker process (JMV)? 2:Should I think executor like a Java Thread Executor where the pool size is equal with the number of the given cores (set up by the SPARK_WORKER_CORES)? 3. If the worker can have many executors, how this is handled by the Spark? Or can I handle by myself to set up the number of executors per JVM?
I look forward for your answers. Regards, Florin
