kafka启用SASL认证后使用kafka-consumer-groups.sh查看消费组报错的问题

解决SASL认证类型kafka在使用kafka-consumer-groups.sh查看消费组数据时，报以下异常的问题

Error: Executing consumer group command failed due to org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment.
java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment.

解决方案：

进入docker容器，非docker部署进入kafka安装地址即可：

进入容器 docker exec -it kafka容器ID bash

进入kafka的配置config文件夹：

cd   /home/zk/kafka_2.11-2.1.1/config

执行命令：

vi consumer-group-ssl.properties

输入内容并保存：

security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-512
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="账号" password="密码";

如图：

 保存配置文件consumer-group-ssl.properties

接着执行命令：

cd   /home/zk/kafka_2.11-2.1.1
./bin/kafka-consumer-groups.sh  --describe --bootstrap-server kafka的IP:kafka的端口--command-config config/consumer-group-ssl.properties --group test-group

 查询消费组数据成功！
