Karen Feng updated SPARK-35636:
-------------------------------
    Description: 
Currently, lambda keys can be referenced outside of the lambda function:

Project [transform(keys#0, lambdafunction(_extract_v1#0, lambda key#0, false)) 
AS a#0]
+- 'Join Cross
    :- Project [kvs#0[lambda key#0].v1 AS _extract_v1#0]
    :  +- LocalRelation <empty>, [kvs#0]
    +- LocalRelation <empty>, [keys#0]

This should be unchanged from the original state:

Project [transform(keys#418, lambdafunction(kvs#417[lambda key#420].v1, lambda 
key#420, false)) AS a#419]
+- Join Cross
    :- LocalRelation <empty>, [kvs#417]
    +- LocalRelation <empty>, [keys#418]
