Miklos Szegedi created YARN-7239: ------------------------------------ Summary: Possible launch/cleanup race condition in ContainersLauncher Key: YARN-7239 URL: https://issues.apache.org/jira/browse/YARN-7239 Project: Hadoop YARN Issue Type: Bug Reporter: Miklos Szegedi
ContainersLauncher.handle() submits the launch job and then adds the job into the collection risking that the cleanup will miss it and return. This should be in reversed order in all 3 instances: {code} containerLauncher.submit(launch); running.put(containerId, launch); {code} The cleanup code the above code is racing with: {code} ContainerLaunch runningContainer = running.get(containerId); if (runningContainer == null) { // Container not launched. So nothing needs to be done. LOG.info("Container " + containerId + " not running, nothing to signal."); return; } ... {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
