dilipbiswal commented on issue #23982: [SQL][MINOR] Reconcile the join types between data frame and sql interface URL: https://github.com/apache/spark/pull/23982#issuecomment-470652269 @dongjoon-hyun One question.. In my understanding, option 2 as per @maropu and @cloud-fan is to not change any existing behaviour but simply add more join types i.e make 'left' optional for left semi join . In that case, do we need any migration doc update ?
