Summary: FSPreemptionThread crash with NullPointerException Key: YARN-9984 URL: https://issues.apache.org/jira/browse/YARN-9984 Project: Hadoop YARN Issue Type: Bug Components: fairscheduler Affects Versions: 3.0.0 Reporter: Wilfred Spiegelenburg Assignee: Wilfred Spiegelenburg When an application is unregistered there is a chance that there are still containers running on a node for that application. In all cases we handle the application missing from the RM gracefully (log a message and continue) except for the FS pre-emption thread. In case the application is removed but some containers are still linked to a node the FSPreemptionThread will crash with a NPE when it tries to retrieve the application id for the attempt: {code:java} FSAppAttempt app = scheduler.getSchedulerApp(container.getApplicationAttemptId()); ApplicationId appId = app.getApplicationId();{code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
