> Right now, we could specify applicationId, node http address and container ID 
> to get the specify container log. Or we could only specify applicationId to 
> get all the container logs. It is very hard for the users to get logs for AM 
> container since the AMContainer logs have more useful information. Users need 
> to know the AMContainer's container ID and related Node http address.
> We could improve the YARN Log Command to allow users to get AMContainer logs 
> directly
