Liu Shaohui commented on HBASE-12863:
-------------------------------------

[~Apache9]
The reason why to get infoPort in this way is that in some cases eg, in yarn, 
we don't know which port is available before we start the http server. So we 
set the hbase.master.info.port to 0, and let the os  assign a port for info 
server.

> Master info port on RS UI is always 0

> Not sure the reason. The link at the bottom of the RS UI back to master 
> always lists 0 as the info port, thus fails when clicked. 
> Any takers ?
