示例1: assign

private synchronized void assign(Priority priority, NodeType type,
List<Container> containers) throws IOException, YarnException {

String host = container.getNodeId().toString();
if (Resources.equals(requestSpec.get(priority), container.getResource())) {

for (Iterator<Task> t=tasks.get(priority).iterator(); t.hasNext();) {
Task task = t.next();
if (task.getState() == State.PENDING && task.canSchedule(type, host)) {
NodeManager nodeManager = getNodeManager(host);
task.start(nodeManager, container.getId());
i.remove();
// Track application resource usage
Resources.addTo(used, container.getResource());
