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).
