------------------------------------
Summary: subscriptionGroup missed after restart
Key: ROCKETMQ-368
URL: https://issues.apache.org/jira/browse/ROCKETMQ-368
Project: Apache RocketMQ
Issue Type: Bug
Components: rocketmq-broker
Affects Versions: 4.1.0-incubating
Environment: Red Hat Enterprise Linux Server release 6.8 (Santiago)
java version "1.8.0_121"
Reporter: superheizai
Assignee: yukon
When we changed IDC infrastructure, the server lost power by accident. When we
found after half an hour, we power on the server and restart the broker.
But then, some teams found that then couldn't consume message from the
restarted server any more, and got an exception, the subscriptionGroup doesn't
exist. I checked the consumerOffset file and subscriptionFile under store path,
I found the subscriptionGroup info in consumerOffset file, but not in the
subscriptionGroup file. At the same file, I found many subscriptionGroup missed
in the subscriptionGroup file.
I fix this by updateSubscriptionGroup command.
