Follow this checklist to help us incorporate your contribution quickly and easily. Notice, it would be helpful if you could finish the following 5 checklist(the last one is not necessary)before request the community to review your PR.

• [x] Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github 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 [ISSUE #123] 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(over 80% coverage) to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
• [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.
• [ ] If this contribution is large, please file an Apache Individual Contributor License Agreement.

org/apache/rocketmq/namesrv/routeinfo/BatchUnRegisterService.java:63 while (!this.isStopped()) {

use poll can make thread graceful stop. maybe this is the original intention

[kang-hl]

it may be more graceful to replace this.unRegisterService.shutdown(true) with this.unRegisterService.shutdown()

[kang-hl]

replacing poll() is better than replacing this.unRegisterService.shutdown() because the queue is empty most of the time
