已启用auto.create.topics.enable=true

1. 没有提前创建topic，直接用kafka-console-producer.sh发布消息，一直都报错LEADER NOT AVAULABLE
2. /kafka-console-producer.sh --broker-list 192.168.26.136:9092,192.168.26.138:9092,192.168.26.139:9092 --topic 444

   zzzzzzzzz

3、提前创建好topic再用kafka-console-producer.sh发布消息就没有报错了，版本kafka_2.11-1.1.0，ZK版本3.4.11
