The reason for this is, wide transformations in Spark requires a shuffle. Operations like join, group by etc. are wide transform operations and they trigger a shuffle.<\/span><\/p>\nBy default, Spark creates 200 partitions whenever there is a need for shuffle. Each partition will be processed by a task. So, you will end up with 200 tasks during execution.<\/span>
