Corey Woodfield created SPARK-21333:
---------------------------------------
Summary: joinWith documents and analysis allow invalid join types
Key: SPARK-21333
URL: https://issues.apache.org/jira/browse/SPARK-21333
Project: Spark
Issue Type: Bug
Components: Documentation
Affects Versions: 2.1.1
Reporter: Corey Woodfield
Priority: Minor
joinWith returns a Dataset<Tuple2>, but left_semi and left_anti (which only
return things from one side of the join) are listed as acceptable join types in
the documentation, and an error is not thrown until spark gets to the joining
part, rather than in the analysis phase. These join types should be removed
from the documentation, and this error should be caught earlier
