damccorm opened a new pull request, #34335: URL: https://github.com/apache/beam/pull/34335
In some cases it is possible for a thread pool executor to hang on cancelled tasks when awaitTermination is called - https://bugs.openjdk.org/browse/JDK-7069418 This attempts to fix the problem by calling [purge](https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ThreadPoolExecutor.html#purge--) which tries to remove from the work queue all Future tasks that have been cancelled. This should hopefully remove the cancelled tasks so that we just need to wait on any in progress ones to complete. I don't have a repro of the initial problem, so I can't be sure this is a fix. But it should be low risk and may resolve the issue ------------------------ Thank you for your contribution!
