Eric Yang commented on YARN-9089:
---------------------------------

I was able to find a shorter workaround without refactoring data that goes into 
Timeline server to obtain node manager port.  Patch 001 works with YARN-8914 
patch 008.

> Add Terminal Link to Service component instance page for UI2

> In UI2, Service > Component > Component Instance uses Timeline server to 
> aggregate information about Service component instance.  Timeline server does 
> not have the full information like the port number of the node manager, or 
> the web protocol used by the node manager.  It requires some changes to 
> aggregate node manager information into Timeline server in order to compute 
> the Terminal link.  For reducing the scope of YARN-8914, it is better file 
> this as a separate task.
