      Description

      While re-enabling the S3PlannerTest in IMPALA-8944, there are several tests that are consistently failing due to actual diffs in the explain plan:

      • org.apache.impala.planner.S3PlannerTest.testTpcds
      • org.apache.impala.planner.S3PlannerTest.testTpch
      • org.apache.impala.planner.S3PlannerTest.testJoinOrder
      • org.apache.impala.planner.S3PlannerTest.testSubqueryRewrite

      All are failing for non-trivial reasons - e.g. differences in memory estimates, join orders, etc.
