linhongliu-db opened a new pull request #33182: URL: https://github.com/apache/spark/pull/33182
### What changes were proposed in this pull request? Add a config `spark.sql.join.forceApplyShuffledHashJoin` to force applying shuffled hash join during the join selection. ### Why are the changes needed? In the `SQLQueryTestSuite`, we want to cover 3 kinds of join (BHJ, SHJ, SMJ) in join.sql. But even if the `spark.sql.join.preferSortMergeJoin` is set to `false`, shuffled hash join is still not guaranteed. Thus, we need another config to force the selection. ### Does this PR introduce _any_ user-facing change? No, only for testing ### How was this patch tested? newly added tests -- This is an automated message from the Apache Git Service.
