This should > be in reversed order in all 3 instances: > {code} > containerLauncher.submit(launch); > running.put(containerId, launch); > {code} > The cleanup code that 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 (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
