| Follow this checklist to help us incorporate your contribution quickly and easily: |
| |
| - [ ] Make sure there is a [JIRA issue](https://issues.apache.org/jira/browse/SCB) 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. |
| - [ ] Each commit in the pull request should have a meaningful subject line and body. |
| - [ ] Format the pull request title like `[SCB-XXX] Fixes bug in ApproximateQuantiles`, where you replace `SCB-XXX` with the appropriate JIRA issue. |
| - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. |
| - [ ] Run `mvn clean install` to make sure basic checks pass. A more thorough check will be performed on your pull request automatically. |
| - [ ] If this contribution is large, please file an Apache [Individual Contributor License Agreement](https://www.apache.org/licenses/icla.pdf). |
