> adding cpu cores will be more accurate I don't think so. The executor slot is a virtual concept for describing how many tasks can be handled concurrently for an executor. It depends on the cpu core number. However, they are different. For some machine, it may be better to assign one tasks for a core. While for others, it may be better to assign two or three. Therefore, here we should use a more general one to indicate the task concurrency. Actually, on our production environment, we leverages the memory size rather than the cpu core number to indicate the task concurrency. The idea is similar to the one used by the Hadoop systems. -- This is an automated message from the Apache Git Service.
