Mighty [~ghelmling]

"what's the reason for undoing it? We've been considering it as a solution to 
situations where the RS hosting meta has a backed up priority queue and master 
cannot complete initialization, or if up and running cannot complete region 
reassignments for failed servers."

I'd undo it because as-is it is half-baked so disabling till done and we decide 
this is the way we want to indeed go (I'd be against it).

+ Because it puts the master in the write path.
+ Won't work for case where we split meta

> After [HBASE-10569|https://issues.apache.org/jira/browse/HBASE-10569], master 
> is also a regionserver and it will serve regions of system tables. The meta 
> region info could be viewed on master at the address such as : 
> http://localhost:16010/region.jsp?name=1588230740. The real path of 
> region.jsp for the request will be hbase-webapps/master/region.jsp on master, 
> however, the region.jsp is under the directory hbase-webapps/regionserver, so 
> that can not be found on master.
