> With [SPARK-21333|https://issues.apache.org/jira/browse/SPARK-21333] change, LeftSemi and LeftAnti no longer has a typesafe join API. It makes sense to not support LeftSemi and LeftAnti as part of joinWith as it returns tuples which includes values from both the datasets which is not possible in the above joins. Neverthless, it would be nice to have a separate join API or in the existing API to support LeftSemi and LeftAnti which returns Dataset.
