Ankur Dave created SPARK-37089: ---------------------------------- Summary: ParquetFileFormat registers task completion listeners lazily, causing Python writer thread to segfault when off-heap vectorized reader is enabled Key: SPARK-37089 URL: https://issues.apache.org/jira/browse/SPARK-37089 Project: Spark Issue Type: Bug Components: PySpark, SQL Affects Versions: 3.2.0, 3.1.2, 3.0.3 Reporter: Ankur Dave Assignee: Ankur Dave
The task completion listener that closes the vectorized reader is registered lazily in ParquetFileFormat#buildReaderWithPartitionValues(). Since task completion listeners are executed in reverse order of registration, it always runs before the Python writer thread can be interrupted. This contradicts the assumption in https://github.com/apache/spark/pull/34245 that task completion listeners are registered bottom-up, preventing that fix from working properly. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
