Bryan Cutler created SPARK-27992: ------------------------------------ Summary: PySpark socket server should sync with JVM connection thread future Key: SPARK-27992 URL: https://issues.apache.org/jira/browse/SPARK-27992 Project: Spark Issue Type: Improvement Components: PySpark Affects Versions: 2.4.3 Environment: Both SPARK-27805 and SPARK-27548 identified an issue that errors in a Spark job are not propagated to Python. This is because toLocalIterator() and toPandas() with Arrow enabled run Spark jobs asynchronously in a background thread, after creating the socket connection info. The fix for these was to catch a SparkException if the job errored and then send the exception through the pyspark serializer.
A better fix would be to allow Python to synchronize on the serving thread future. That way if the serving thread throws an exception, it will be propagated on the synchronization call.
