Error while fetching metadata with correlation id 10 : {monitor-desc-pedestrian-attr-recog_gpu-task-nod1=LEADER_NOT_AVAILABLE}

config配置server.properties
解决：

#     listeners = PLAINTEXT://your.host.name:9092

去掉注释，将各主机本地ip替换“your.host.name”，重启后恢复正常。

ZkClient: zookeeper state changed (SyncConnected)

客户端 和服务器连接时版本问题，即pom中的版本和工具的版本不一致，

kafka java.util.concurrent.TimeoutException: Timeout after waiting for 5000 ms.
