From b712c2d815dc605f1cbaf7ccd378eaa28307d5e2 Mon Sep 17 00:00:00 2001 From: MithunR Date: Thu, 26 Sep 2024 12:02:33 -0700 Subject: [PATCH 1/2] Spark 4: Fix parquet_test.py. Fixes #11015. Contributes to #11004. This commit addresses the tests that fail in parquet_test.py, when run on Spark 4. 1. Some of the tests were failing as a result of #5114. Those tests have been disabled, at least until we get around to supporting aggregations with ANSI mode enabled. 2. `test_parquet_check_schema_compatibility` fails on Spark 4 regardless of ANSI mode, because it tests implicit type promotions where the read schema includes wider columns than the write schema. This will require new code. The test is disabled until #11512 is addressed. 3. `test_parquet_int32_downcast` had an erroneous setup phase that fails in ANSI mode. This has been corrected. The test was refactored to run in ANSI and non-ANSI mode.
