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

Example 6 with Offer

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

the class SingularityMesosSchedulerClient method decline.

Example 7 with Offer

use of org.apache.mesos.v1.Protos.Offer 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
