unit tests when enable AQE
URL: https://github.com/apache/spark/pull/26813#issuecomment-580336242
 
 
   I did not go through the entire list of changes. I've noticed these 
categories of changes so far:
   1. Fix: 
https://github.com/apache/spark/pull/26813/files/8b5e7442c63fe326db7c7f46f7a194fbae8f0d46#diff-f0ed5bcd435a874d4eb2faf0c2a1b091R33
   2. Things I'm not sure if they are correctness issue workaround or 
performance optimization:

   3. Use of AdaptiveSparkPlanHelper to resolve leaf node issues and hard-code 
plan checks.
   4. Ordering results using "sort"
   5. Disabling AQE flags: e.g., SQLMetricsSuite,

   A big +1 on (3).
   Let's pull (1) into different PRs for easy tracking.
   Let's verify (2) and see what to do.
   Look into (4) and at least understand why. I'm sure some of these changes 
are legitimate, but users may find results to be different when turning on AQE.
   Pull them out into different PRs, and open a JIRA ticket for each of these 
tests in (5).
