Review comment:
You can use ExpectedLogs as a test rule to capture whether output was
produced or not instead of abstracting out a getHotKeyMessage. See
https://github.com/apache/beam/blob/cfca7f176acb3542c7b86312f968819a1e97866e/sdks/java/core/src/test/java/org/apache/beam/sdk/coders/SerializableCoderTest.java#L259
for an example.

Review comment:
you should rely on slf4j for log formatting with parameters as we won't
pay the cost of forming the string if logging is disabled. e.g.:
```LOG.warn("my message with param 1 {}, param 2 {}", param1, param2);```
