Examples with WorkerPorts io.mantisrx.common.WorkerPorts used on opensource projects

Example 1 with WorkerPorts

use of io.mantisrx.common.WorkerPorts in project mantis by Netflix.

the class SchedulingService method launchTasks.

/**
 * Attempts to launch tasks given some number of leases from Mesos.
 *
 * When a task is launched successfully, the following will happen:
 *
 * 1. Emit a {@link WorkerLaunched} event to be handled by the corresponding actor.
 * 2. Makes a call to the underlying Mesos driver to launch the task.
 *
 * A task can fail to launch if:
 *
 * 1. It doesn't receive enough metadata for {@link WorkerPorts} to pass its preconditions.
 *      - No launch task request will be made for this assignment result.
 *      - Proactively unschedule the worker.
 * 2. It fails to emit a {@link WorkerLaunched} event.
 *      - The worker will get unscheduled for this launch task request.
 * 3. There are no launch tasks for this assignment result.
 *      - All of these leases are rejected.
 *      - Eventually, the underlying Mesos driver will decline offers since there are no launch task requests.
 *
 * @param requests collection of assignment results received by the scheduler.
 * @param leases list of resource offers from Mesos.
