我已经创建了一个带有喷口的storm拓扑，该喷口发出许多元组以进行基准测试。一旦所有元组都从喷口发出或者拓扑中不再有元组流动，我就想停止/终止我的拓扑。
这是我的拓扑图。

LocalCluster cluster = new LocalCluster();
TopologyBuilder builder = new TopologyBuilder();
Config conf = new Config();
//Disabled ACK'ing for higher throughput
conf.put(Config.TOPOLOGY_ACKER_EXECUTORS, 0); 

LoadGeneratorSource loadGenerator = new LoadGeneratorSource(runtime,numberOfTuplesToBeEmitted);
builder.setSpout("loadGenerator", loadGenerator);

//Some Bolts Here

while (loadGenerator.isRunning()){
//Active Waiting
}
//DO SOME STUFF WITH JAVA
cluster.killTopology("StormBenchmarkTopology");

问题是我在这个范围内引用的loadgenerator示例与在spout线程中运行的不同。因此，isrunning（）总是返回true，即使在喷口线程中，当没有更多元组要发出时，它的值是false。
这里是loadgeneratorsource类的一部分。

public class LoadGeneratorSource extends BaseRichSpout {

    private final int throughput;
    private boolean running;
    private final long runtime;

    public LoadGeneratorSource(long runtime,int throughput) {
        this.throughput = throughput;
        this.runtime = runtime;
    }

    @Override
    public void nextTuple() {
        ThroughputStatistics.getInstance().pause(false);

        long endTime = System.currentTimeMillis() + runtime;
        while (running) {
            long startTs = System.currentTimeMillis();

            for (int i = 0; i < throughput; i++) {
                try {
                    emitValue(readNextTuple());
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            while (System.currentTimeMillis() < startTs + 1000) {
                // active waiting
            }

            if (endTime <= System.currentTimeMillis())
                setRunning(false);
        }
    }

    public boolean isRunning() {
        return running;
    }

    public void setRunning(boolean running) {
        this.running = running;
    }

    //MORE STUFF

}

有人能告诉我一种方法来停止我的拓扑一旦有更多的元组发射从喷口或流动的拓扑？提前谢谢你的帮助。
