EventListeners can interrupt the event queue thread. In particular, when the EventLoggingListener writes to hdfs, hdfs can interrupt the thread. When there is an interrupt, the queue should be removed and stop accepting any more events. Before this change, the queue would continue to take more events (till it was full), and then would not stop when the application was complete because the PoisonPill couldn't be added. Added a unit test which failed before this change. Author: Imran Rashid <irashid@cloudera.com> Closes #21356 from squito/SPARK-24309. |
