             Summary: Log the command of launching containers
                 Key: YARN-3755
                 URL: https://issues.apache.org/jira/browse/YARN-3755
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Jeff Zhang


In the resource manager, yarn would log the command for launching AM, this is very useful. But there's no such log in the NN log for launching containers. It would be difficult to diagnose when containers fails to launch due to some issue in the commands. Although use can look at the commands in the container launch script file, this is an internal things of yarn, usually user don't know that. In user's perspective, they only know what command they specify when building yarn application.
