--------------------------------------------------------------

Thanks [~xgong], yes this is an issue. I am thinking if the customer needs to 
customize the location of the logs, and choose not to upload the logs into the 
configured RemoteRootDir assumed by Yarn, then I assume they will handle the 
downstream log usage, and it is okay for yarn log cli and RM UI not to be able 
to find it? 

Or in their private implementation, they can copy the logs to both places. One 
for Yarn to understand, and one for their customized use.
