   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](https://github.com/apache/rocketmq/issues) 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](https://github.com/apache/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.
   - [ ] If this contribution is large, please file an [Apache Individual Contributor License Agreement](http://www.apache.org/licenses/#clas).

Review Comment:
   Set `waitTimeThreshold` to could ensure that all data could send out in 1000ms.
   
   > 将`waitTimeThreshold`设置为500ms可以保证数据在本地保存时间不超过1000ms,因为有些很早放入的数据可能持续到下一次检查才会’过时‘。如果想尽可能及时的发送超时waitTimeThreshold的数据可修改endTime获取逻辑、如下。
   ```
   long endTime = System.currentTimeMillis() + waitTimeThreshold / 2;
