@davies @JoshRosen Could you check if this PR is appropriate? Thanks! |

LGTM, merging into master and 1.6 (for doc). I think it's fine to not fix 1.5 branch, until some one hit it, because we may not have a new release for 1.5 branch. |

…i-Join After reading the JIRA https://issues.apache.org/jira/browse/SPARK-12520, I double checked the code. For example, users can do the Equi-Join like ```df.join(df2, 'name', 'outer').select('name', 'height').collect()``` - There exists a bug in 1.5 and 1.4. The code just ignores the third parameter (join type) users pass. However, the join type we called is `Inner`, even if the user-specified type is the other type (e.g., `Outer`). - After a PR: #8600, the 1.6 does not have such an issue, but the description has not been updated. Plan to submit another PR to fix 1.5 and issue an error message if users specify a non-inner join type when using Equi-Join. Author: gatorsmile <[email protected]> Closes #10477 from gatorsmile/pyOuterJoin.
