当我尝试通过Producer API将消息插入Kafka时遇到以下错误
function filterDates(){
var list = document.getElementById("myList"); //wanted substring from first of the string to the first space
var listItems = Array.from(list.children); //list.children is not actually an array
list.innerHTML = "" //make the list empty
var now = new Date(); //current time
var filteredList = listItems.filter(function(li){
var dateString = li.innerHTML.split(' ')[0];
var splited = dateString.split('/') //it is an array: [MM, DD, YYYY]
var dateToCheck = new Date(splited[2], splited[0], splited[1]); // new Date(year, month, day)
return dateToCheck.getTime() > now.getTime();
})
filteredList.forEach(function(el){
list.appendChild(el);
})
}
这可能是什么问题？
更多代码如下：
org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s) for metadata_notification-0: 30036 ms has passed since batch creation plus linger time
此时，它失败了，并给出了上面的错误-TimeoutException
protected void produceMessage(String topic, String orgId, Map<String, byte[]> header, String payload) throws Exception {
System.out.println("In Produce Message Method");
final Producer<String, String> producer = createMetaProducer();
long time = System.currentTimeMillis();
try {
List<Header> messageHeaders = header.entrySet().stream().map(e -> new RecordHeader(e.getKey(), e.getValue())).collect(Collectors.toList());
System.out.println("Send header");
LOGGER.info("Sending headers:");
for(Header mh: messageHeaders) {
LOGGER.info("{}: {}",mh.key(),new String(mh.value()));
}
final ProducerRecord<String, String> record = new ProducerRecord<>(topic, null, orgId, payload, messageHeaders);
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("sent record(key=%s value=%s) " +
"meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
} finally {
producer.flush();
producer.close();
}
}
在我的情况下，kafka是码头工人形象
