Ryan Wu created YARN-10459: ------------------------------ Summary: containerLaunchedOnNode method not need to hold schedulerApptemt lock Key: YARN-10459 URL: https://issues.apache.org/jira/browse/YARN-10459 Project: Hadoop YARN Issue Type: Improvement Affects Versions: 3.1.3, 3.2.0 Reporter: Ryan Wu Fix For: 3.2.1
Now, the containerLaunchedOnNode hold the SchedulerApplicationAttempt writelock, but looking at the method, it does not change any field. And more seriously, this will affect the scheduler public void containerLaunchedOnNode(ContainerId containerId, NodeId nodeId) { // Inform the container writelock.lock try \{ RMContainer rmContainer = getRMContainer(containerId); if (rmContainer == null) { // Some unknown container sneaked into the system. Kill it. rmContext.getDispatcher().getEventHandler().handle( new RMNodeCleanContainerEvent(nodeId, containerId)); return; } rmContainer.handle( new RMContainerEvent(containerId, RMContainerEventType.LAUNCHED)); }finally { writeLock.unlock(); } } -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
