URL: https://github.com/apache/rocketmq/issues/3257
**BUG REPORT**
1. Please describe the issue you observed:
- What did you do?
Create an empty file under $storePathCommitLog directory. Say, you have
commit log store under /data0/rocketmq/commitlogs/,
then you create a file named 'the-bad-empty-file-fails-rocketmq-startup".
Restart broker.
Then the broker will not be able to startup normal.
You may see error message like "the-bad-empty-file-fails-rocketmq-startup 0
length not matched message store value. please check it manually" in the
storeerror.log.
- What did you expect to see?
Even in this case, RocketMQ broker should startup normally and log a warning
message.
- What did you see instead?
RocketMQ broker does not startup and does not explain the reason clearly.
2. Please tell us about your environment:
It's an ordinary CentOS 7.5 running Intel x86 chip on bare metal.
3. Other information (e.g. detailed explanation, logs, related issues,
suggestions how to fix, etc):
This suggestion is to ignore file length is not same as mappedFileSize which
is 1G by default. Log a warning and continue to start.
