There are a variety of REST API services you can use, but you must consider carefully whether it makes sense to start a Spark job based on individual requests, unless you mean based on some triggering event you want to start a Spark job, in which case it makes sense to use the RESTful service. Whether your Spark cluster is multi-tenant depends on the scheduler you use, cluster size and other factors. But you seem to be mixing terminology, a given application can certainly generate many tasks and you could deploy many applications on a single Spark cluster, whether you do them all concurrently or not is where the issue of multi-tenancy comes into picture.
