The problem can be reproduced by following steps: 1. Start a RocketMQ cluster with 2 brokers; 2. When no subscription exists, that is, the file `/root/store/config/subscriptionGroup.json` in broker-0-master-0 does NOT exists, increase the size of cluster; 3. The added brokers will failed to start because `/root/store/config/subscriptionGroup.json` contains `<nil>`, which is an invalid JSON string. Causeļ¼ When the actual size of cluster is less than the specified number, the broker controller will create new brokers, and copy `subscriptionGroup.json` in broker-0-master-0 to the added brokers. However, if that file does not exists, `controller/broker.exec` just returns a string "<nil>", which is copied to the added brokers. -- This is an automated message from the Apache Git Service.
