use of org.apache.myriad.scheduler.constraints.Constraint in project incubator-myriad by apache.

the class MyriadOperations method flexDownTasks.

private int flexDownTasks(Collection<Protos.TaskID> taskIDs, ServiceResourceProfile profile, Constraint constraint, int numInstancesToScaleDown) {
    int numInstancesScaledDown = 0;
    for (Protos.TaskID taskID : taskIDs) {

        if (nodeTask.getProfile().getName().equals(profile.getName()) && meetsConstraint(nodeTask, constraint)) {
            this.schedulerState.makeTaskKillable(taskID);
            numInstancesScaledDown++;
            if (numInstancesScaledDown == numInstancesToScaleDown) {
                break;
            }
