Linhong Liu created SPARK-35984:
-----------------------------------

             Summary: Add a config to force using ShuffledHashJoin for test purpose
                 Key: SPARK-35984
                 URL: https://issues.apache.org/jira/browse/SPARK-35984
             Project: Spark
          Issue Type: Task
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Linhong Liu


In the join.sql, we want to cover all 3 join types. but the problem is currently the `spark.sql.join.preferSortMergeJoin = false` couldn't guarantee all the joins will use ShuffledHashJoin, so we need another config to force using hash join in the testing.
