---------------------------------------
huxihx commented on pull request #6066: KAFKA-7763: commitTransaction and
abortTransaction should not wait endless when brokers are down
URL: https://github.com/apache/kafka/pull/6066
Currently, commitTransaction and abortTransaction invoke Latch#await to wait
for the request completion. When brokers are not available, these calls await
forever and producer never ends. This fix replaces it with the timed equivalent
await(timeout, unit). When timeout occurred, producer throws a TimeoutException.

> When the client disconnect with the bootstrap server, a KafkaProducer with

> https://issues.apache.org/jira/browse/KAFKA-6446
> the reproduce condition you can do it as belows:
> 1、producer.initTransactions();
> 2、producer.beginTransaction();
> 3、producer.send(record1);//set the breakpoint here
> key step: run the breakpoint above 3 then disconnect the network by manual,
> 10-20seconds recover the network and continute the program by canceling the
> breakpoint
> 4、producer.send(record2);
> 5、producer.commitTransaction();//endless waits
