Kafka is a very nice software , and we have been using it for a long time. But now ,I encountered a problem. When I create a topic on kafka server cluster, the leader of every partition is none . like this: The command is : /opt/apps_install/kafka_2.9.2-0.8.1/bin/kafka-topics.sh --zookeeper 10.16.10.94:2181/kafka-0.8.1<http://10.16.10.94:2181/kafka-0.8.1> --create --topic meteor_hot_article3 --replica-assignment 4:7,5:8:2,6:9 The zookeeper server cluster is normal and no kafka server is down，everything looks normal. Then I use this command : /opt/apps_install/kafka_2.9.2-0.8.1/bin/kafka-topics.sh --zookeeper 10.16.10.94:2181/kafka-0.8.1<http://10.16.10.94:2181/kafka-0.8.1> --create --topic topicName --partitions 10 --replication-factor 3 The leader is none too. I am desperate and I don’t know what to do ,so please help me . My kafka version is 2.9.2-0.8.1. zookeeper version is 3.4.5. -- News, jobs, product releases, events.
