[SPARK-12602] [SQL] Join Reordering: Pushing Inner Join Through Left/Right Outer Join This PR is to push `Inner Join` through `Left/Right Outer Join`. This can reduce the number of processed rows since the `Inner Join` always can generate less rows than `Left/Right Outer Join`. This PR can improve the query performance, if applicable. For example, TODO: added test cases into optimizer buckets.
