Examples with OfferID org.apache.mesos.v1.Protos.OfferID used on opensource projects

Example 1 with OfferID

use of org.apache.mesos.v1.Protos.OfferID in project Singularity by HubSpot.

the class SingularityMesosSchedulerClient method decline.

/**
 * Sent by the scheduler to explicitly decline offer(s) received. Note that this is same as sending an
 * ACCEPT call with no operations.
 *
 * @param offerIds
 */
public void decline(List<OfferID> offerIds) {

Example 2 with OfferID

use of org.apache.mesos.v1.Protos.OfferID in project Singularity by HubSpot.

the class SingularityMesosSchedulerClient method accept.

/**
 * Sent by the scheduler when it accepts offer(s) sent by the master. The ACCEPT request includes the type of
 * operations (e.g., launch task, launch task group, reserve resources, create volumes) that the scheduler wants to
 * perform on the offers. Note that until the scheduler replies (accepts or declines) to an offer, the offer’s
 * resources are considered allocated to the offer’s role and to the framework.
 *
 * @param offerIds
 * @param offerOperations
