HyukjinKwon opened a new pull request #35423: URL: https://github.com/apache/spark/pull/35423
### What changes were proposed in this pull request? This PR proposes to show full stacktrace of Python worker and JVM in PySpark by controlling `spark.sql.pyspark.jvmStacktrace.enabled` and `spark.sql.execution.pyspark.udf.simplifiedTraceback.enabled` only in tests. ### Why are the changes needed? [SPARK-33407](https://issues.apache.org/jira/browse/SPARK-33407) and [SPARK-31849](https://issues.apache.org/jira/browse/SPARK-31849) hide Java stacktrace and internal Python worker side traceback by default for simpler error messages to end users. However, specifically for unit tests, that makes a bit harder to debug the test failures. We should probably show the full stacktrace by default in tests. ### Does this PR introduce _any_ user-facing change? No, this is test only. ### How was this patch tested? Manually tested. Now the test failures show the logs as below: ``` ====================================================================== ERROR [3.259s]: test (pyspark.sql.tests.test_functions.FunctionsTests) ---------------------------------------------------------------------- Traceback (most recent call last): ... pyspark.sql.utils.PythonException: An exception was thrown from the Python worker.
