### What changes were proposed in this pull request? This is a followup of #32586. We introduced `ExpressionContainmentOrdering` to sort common expressions according to their parent-child relations. For unrelated expressions, previously the ordering returns -1 which is not correct and can possibly lead to transitivity issue. ### Why are the changes needed? To fix the possible transitivity issue of `ExpressionContainmentOrdering`. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Unit test. Closes #32870 from viirya/SPARK-35439-followup. Authored-by: Liang-Chi Hsieh <viirya@gmail.com> Signed-off-by: Takeshi Yamamuro <yamamuro@apache.org> |
