Local mode
Local mode runs both driver and executors on a single machine. In this mode, the partitions are processed by multiple threads in parallel. The number of threads can be controlled by the user while submitting the job. This mode is useful in the learning phase but, not recommended for production applications, as you only use a single machine to process the data.
