kafka找不到消费组 Consumer group ... has no active members

flink1.10.1从kafka拉取数据计算，能正常发送和消费数据，但是找不到消费组member-risk-flink

Properties properties = new Properties();
properties.setProperty("bootstrap.servers", kafkaServers);

properties.setProperty("max.poll.records", kafkaOffset);
DataStreamSource<String> dataStream = env.addSource(new FlinkKafkaConsumer011(calculateInputTopic, new SimpleStringSchema(), properties));

MacBook-Pro-3:kafka_2.12-0.11.0.1 zc$ bin/kafka-consumer-groups.sh --bootstrap-server 10.9.253.80:9092 --delete --group member-risk-flink
Option '[delete]' is only valid with '[zookeeper]'. Note that there's no need to delete group metadata for the new consumer as the group is deleted when the last committed offset for that group expires.

MacBook-Pro-3:kafka_2.12-0.11.0.1 zc$ bin/kafka-consumer-groups.sh --zookeeper 10.9.253.80:2181  --delete --group member-risk-flink
Note: This will only show information about consumers that use ZooKeeper (not those using the Java consumer API).

Error: Delete for group 'member-risk-flink' failed because group does not exist.
