org.apache.rocketmq.remoting.exception.RemotingTimeoutException: invokeSync call timeout

==问题==

在本地Debug调试Flink消费RocketMQ数据的时候，提示如下错误

==解决办法==

RocketMQ集群版本是：4.6.1

程序中依赖的客户端版本也是4.6.1

<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-client</artifactId>
    <version>4.6.1</version>
</dependency>
<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-acl</artifactId>
    <version>4.6.1</version>
</dependency>

 

有网友建议降低客户端版本为4.5.0，尝试了一下，确实可以解决。
