DESCRIPTION HERE
------------------------
Follow this checklist to help us incorporate your contribution quickly and
easily:
- [ ] Make sure there is a [JIRA
issue](https://issues.apache.org/jira/projects/BEAM/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.
- [ ] Format the pull request title like `[BEAM-XXX] Fixes bug in
ApproximateQuantiles`, where you replace `BEAM-XXX` with the appropriate JIRA
issue.
- [ ] Write a pull request description that is detailed enough to
understand:
- [ ] What the pull request does
- [ ] Why it does it
- [ ] How it does it
- [ ] Why this approach
- [ ] Each commit in the pull request should have a meaningful subject line
and body.
- [ ] Run `mvn clean verify` 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).

> "Note: if the input collection uses a windowing strategy other than
> GlobalWindows, use Combine.globally(Count.<T>combineFn()).withoutDefaults()
> instead."
> But the actual crash a user gets is:
> "java.lang.IllegalStateException: Default values are not supported in
> Combine.globally() if the output PCollection is not windowed by
> GlobalWindows. Instead, use Combine.globally().withoutDefaults() to output an
> empty PCollection if the input PCollection is empty, or
> Combine.globally().asSingletonView() to get the default output of the
> CombineFn if the input PCollection is empty."
> There is a method that exists solely to make this actually useful, so we
> should use it!
