wangshisan opened a new pull request #29266: URL: https://github.com/apache/spark/pull/29266
### What changes were proposed in this pull request? Support skew handling on join that has one side with no query stage. ### Why are the changes needed? In our production environment, there are many bucket tables, which are used to join with other tables. And there are some skewed joins now and then. While, in current implementation, the skew join handling can only applied when both sides of a SMJ are QueryStages. So skew join handling is not able to deal with such cases. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested?
