> ----------------------------------------------------------------------------
>
> Key: SPARK-20232
> URL: https://issues.apache.org/jira/browse/SPARK-20232
> Project: Spark
> Issue Type: Improvement

> Affects Versions: 2.1.0
> Environment: macOS Sierra 10.12.4
> Spark 2.1.0 installed via Homebrew
> Reporter: David Gingrich
> Assignee: David Gingrich

> combineByKey docs has a few flaws:

> are add)
> I have a trivial patch, will attach momentarily.
