bq. is there a JIRA for the longer term fix?

Yeah, I've filed YARN-3761 previously.

> YARN-2971 changes TimelineClient to use the service address from Timeline DT 
> to renew the DT instead of configured address. This break the procedure of 
> submitting an YARN app via REST API in the secure mode.
> The problem is that service address is set by the client instead of the 
> server in Java code. REST API response is an encode token Sting, such that 
> it's so inconvenient to deserialize it and set the service address and 
> serialize it again.
