> application:application_1445832014581_0028
> This application:application_1445832014581_0028 is finished. Please enable 
> the application history service. Or Using yarn logs -applicationId <appId>

> {noformat}
> Part of the command output mentioned above indicates that using {{yarn logs 
> -applicationId <appId> -containerId <containerId> --nodeAddress 
> <nodeHttpAddress>}} will fetch desired result. It asks you to specify 
> nodeHttpAddress which makes it sound like we have to connect to nodemanager's 
> webapp address.
> This help message should be changed to include command as {{yarn logs 
> -applicationId <appId> -containerId <containerId> --nodeAddress <Node 
> Address>}}
