Michael Feimen, a principal product architect at IBM, and Shinnosuke Okada a software engineer with Spark team at IBM discusses the importance of the dynamic service-level agreement (SLA) control for Spark applications that are implemented through resource allocation priorities.
These can be assigned to each Spark application at submission and then dynamically modified during the whole lifecycle of the application. The Spark application priority is translated by the scheduler to resource allocation adjustments for executors, and include either preemptive or non-preemptive release of resources. The priorities translation algorithm is determined by a scheduling policy to either define the order of executor allocations between applications or calculate the priority-weighed allocation shares among all submitted applications from the entire resource pool.
