At completion of execution of the first task by the cluster, the driver retains for a second task among the plurality of tasks at least a portion of the resources allocated to the first task by the cluster manager. The driver determines a second quantity of the resources to retain for the second task based on a relative priority of the job to other jobs in the cluster and efficiency of the cluster manager in allocating resources to the first task.
