下面是addSink的代码：
result.addSink(new FlinkKafkaProducer(DataSourceConfig.ResultTopic,new
MyKafkaSerializationSchema(DataSourceConfig.ResultTopic),ConnectToKafka.getKafKaProducerProperties(),FlinkKafkaProducer.Semantic.EXACTLY_ONCE,
3)).setParallelism(1);
KafkaProducer配置信息：
props_Producer.put("bootstrap.servers",
DataSourceConfig.bootstrapServersIPAddress);
props_Producer.put("acks","all");
props_Producer.put("request.timeout.ms", 3000);
总之我也不太清楚为什么会反复打印下面的链接时才会打印的log，推测是一直在重新连接，几乎无间断的打印下面的log给磁盘撑爆了。请教各位大佬可能的原因？
