Spark applications are run in the form of independent processes that are well coordinated by the Driver program by means of a SparkSession object. The cluster manager or the resource manager entity of Spark assigns the tasks of running the Spark jobs to the worker nodes as per one task per partition principle. There are various iterations algorithms that are repeatedly applied to the data to cache the datasets across various iterations. Every task applies its unit of operations to the dataset within its partition and results in the new partitioned dataset. These results are sent back to the main driver application for further processing or to store the data on the disk.
