dilipbiswal edited a comment on issue #23982: [SQL][MINOR] Reconcile the join types between data frame and sql interface URL: https://github.com/apache/spark/pull/23982#issuecomment-469910613 @dongjoon-hyun Thanks.. I totally understand :-). So here are the options : 1) Do nothing 2) Make LEFT mandatory. Its in theory a breaking change. I thought we can simplify stuffs in a major release. We could put a couple of lines in documentation asking users to add the LEFT keyword on a parsing failure. In reality i expect very very few users to be directly using this join type as very few databases expose this join type to users. Thats just my guess .. 3) Make LEFT optional for semi join for pairty with the ANTI join counter-part and expose "semi" and "anti" as join types from dataframe. 4) Perhaps there is another option ?? :-)
