示例1: startTaskTrackers
import org.apache.hadoop.tools.rumen.RackNode; //导入依赖的package包/类
/**
* Start simulated task trackers based on topology.
* @param clusterStory The cluster topology.
* @param now
* time stamp when the simulator is started, {@link SimulatorTaskTracker}s
* are started shortly after this time stamp
*/
void startTaskTrackers(ClusterStory clusterStory, long now) {
/** port assigned to TTs, incremented by 1 for each TT */
int port = 10000;
long ms = now + 100;
for (MachineNode node : clusterStory.getMachines()) {
String hostname = node.getName();
RackNode rackNode = node.getRackNode();
StaticMapping.addNodeToRack(hostname, rackNode.getName());
String taskTrackerName = "tracker_" + hostname + ":localhost/127.0.0.1:"
+ port;
port++;
SimulatorTaskTracker tt = new SimulatorTaskTracker(jt, taskTrackerName,
hostname, node.getMapSlots(), node.getReduceSlots());
queue.addAll(tt.init(ms++));
