The server disconnected before a response was received，going to request metadata update now
kafka
问题现象
往kafka写入数据的时候，出现如下异常：
org.apache.kafka.common.errors.NetworkException: The server disconnected before a response was received，going to request metadata update now
同时kafka server.log有类似的Attempting to send response via channel for which there is no open connection异常。
目前所作的检查
检查Kafka集群网络，目前网络是正常的。
对于这种问题，还望大佬能帮忙看看是啥问题。
