------------------------------------
Summary: PlannerTest differences when running on S3 vs HDFS
Key: IMPALA-8949
URL: https://issues.apache.org/jira/browse/IMPALA-8949
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Sahil Takiar
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.
