Hi [~gtCarrera], IIUC YARN-3488 is talking about if this server side 
configuration is configured differently in the client then though the user 
calls the right API's based on the client side ATS version, it will not be 
successfull in the server. 
So was wondering while starting of the timelineclient whether we can connect to 
the backend timeline server and check whether the server is for the specified 
ATS version in the client, or as YARN-3488 suggests receive the information 
related to the ATS version as part of RM register.Thoughts ?
