I think the check for `SortMergeJoinExec` in `insertInputAdapter` should be
corrected to:
private def insertInputAdapter(plan: SparkPlan): SparkPlan = plan match
{
case p if !supportCodegen(p) =>
// collapse them recursively
InputAdapter(insertWholeStageCodegen(p))
case j @ SortMergeJoinExec(_, _, _, _, left, right) =>
// The children of SortMergeJoin should do codegen separately.
j.copy(left = InputAdapter(insertWholeStageCodegen(left)),
right = InputAdapter(insertWholeStageCodegen(right)))
case p =>
p.withNewChildren(p.children.map(insertInputAdapter))
}
Can you try it? Thanks.
