Xuan Gong updated YARN-3347:
----------------------------
    Description: 
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
