Follow this checklist to help us incorporate your contribution quickly and
easily:
- [x] Make sure there is a [JIRA issue](
https://issues.apache.org/jira/projects/ROCKETMQ/issues/) filed for the
change (usually before you start working on it). Trivial changes like typos
do not require a JIRA issue. Your pull request should address just this
issue, without pulling in other changes - one PR resolves one issue.
- [x] Format the pull request title like `[ROCKETMQ-XXX] Fix
UnknownException when host config not exist`. Each commit in the pull
request should have a meaningful subject line and body.
- [x] Write a pull request description that is detailed enough to
understand what the pull request does, how, and why.
- [x] Write necessary unit-test to verify your logic correction, more mock
a little better when cross module dependency exists. If the new feature or
significant change is committed, please remember to add integration-test in
[test module](https://github.com/apache/incubator-rocketmq/tree/master/test
).
- [x] Run `mvn -B clean apache-rat:check findbugs:findbugs
checkstyle:checkstyle` to make sure basic checks pass. Run `mvn clean
install -DskipITs` to make sure unit-test pass. Run `mvn clean test-compile
failsafe:integration-test` to make sure integration-test pass.
