WebBy “job”, in this section, we mean a Spark action (e.g. save , collect) and any tasks that need to run to evaluate that action. Spark’s scheduler is fully thread-safe and supports this use case to enable applications that serve multiple requests (e.g. queries for multiple users). By default, Spark’s scheduler runs jobs in FIFO fashion. WebDec 1, 1999 · Abstract. Parallel machine scheduling problems concern the scheduling of n jobs on m machines to minimize some function of the job completion times.
