### What changes were proposed in this pull request? author: BoleynSu closes #18836 ```Scala val df = Seq((1, 1)).toDF("i", "j") df.createOrReplaceTempView("T") withSQLConf(SQLConf.AUTO_BROADCASTJOIN_THRESHOLD.key -> "-1") { sql("select * from (select a.i from T a cross join T t where t.i = a.i) as t1 " + "cross join T t2 where t2.i = t1.i").explain(true) } ``` The above code could cause the following exception: ``` SortMergeJoinExec should not take Cross as the JoinType java.lang.IllegalArgumentException: SortMergeJoinExec should not take Cross as the JoinType at org.apache.spark.sql.execution.joins.SortMergeJoinExec.outputOrdering(SortMergeJoinExec.scala:100) ``` Our SortMergeJoinExec supports CROSS. We should not hit such an exception. This PR is to fix the issue. ### How was this patch tested? Modified the two existing test cases. Author: Xiao Li <gatorsmile@gmail.com> Author: Boleyn Su <boleyn.su@gmail.com> Closes #18863 from gatorsmile/pr-18836.
