这是我的输入喷口的代码片段，用于将元组发送到节点以通过集群进行流处理。问题是 BlockingQueue 抛出 InterruptedException 。
private SpoutOutputCollector collector;
public BlockingQueue<String> blockingQueue = new LinkedBlockingQueue<String>();
public boolean isDistributed() {
return true;
}
public void open(@SuppressWarnings("rawtypes") final Map conf, final TopologyContext context,
final SpoutOutputCollector collector) {
this.collector=collector;
}
@Override
public void nextTuple() {
try {
//Utils.sleep(100);
collector.emit(new Values("Single Temperature Reading", blockingQueue.take()));
} catch (InterruptedException e) {
e.printStackTrace();
}
}
public void readInputfile() throws IOException, InterruptedException{
FileInputStream file = new FileInputStream("/home/529076/Desktop/Temperature");
DataInputStream readDate=new DataInputStream(file);
BufferedReader readText=new BufferedReader(new InputStreamReader(readDate));
String line;
String singleReading = null;
while((line=readText.readLine())!=null){
singleReading=line;
blockingQueue.add(singleReading);
}
}
@Override
public void declareOutputFields(OutputFieldsDeclarer declarer) {
declarer.declare(new Fields("Single Temperature Reading"));
}
异常描述如下:---
java.lang.InterruptedException10930 [Thread-20] INFO backtype.storm.util - 异步循环中断!

而 nextTuple(InputStreamSpout.java:65 是 ------>
collector.emit(new Values("Single Temperature Reading", blockingQueue.take()));
谢谢
最佳答案
该错误是由于以下事实造成的:阻塞队列未在输出收集器中初始化；
关于java - 对 BlockingQueue java 和 Storm(分布式计算)的实现有问题吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11343299/
