topic creat完成后准备使用console-produce发布一个topic，错误如下：

[2018-06-12 14:51:15,514] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 3 : {first=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)[2018-06-12 14:51:15,655] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 4 : {first=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)[2018-06-12 14:51:15,761] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 5 : {first=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)[2018-06-12 14:51:15,868] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 6 : {first=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)[2018-06-12 14:51:15,975] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 7 : {first=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)[2018-06-12 14:51:16,083] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 8 : {first=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)[2018-06-12 14:51:16,189] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 9 : {first=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

解决方案：

修改kafka的server.properties的配置

listeners=PLAINTEXT://:9092

修改为

port=9092host.name=x.x.x.x #配置相应的服务器的IP地址即可。

重启后，生效。
