I think you're chasing a rabbit down its hole, Clay. Those are static
methods on RpcServer. You don't need an instance of RpcServer to invoke
them :)
(If there's still a larger question about getting RegionServerServices
that is orthogonal to just the client-IP, let me know. Ignoring the rest
of the details for the moment..)

Hi Josh,
Erg, I see all my MUA stripped my in-line links from the original mail; sorry
for the lack of context.
Yes, the RpcServer API is intact. But I don't see how to get access to an
RpcServer object from a coprocessor now?
Previously, I would have done on my coprocessor's environment object
getRegionServerSerivces():
({https://hbase.apache.org/1.2/apidocs/org/apache/hadoop/hbase/coprocessor/RegionCoprocessorEnvironment.html#getRegionServerServices--})
But now that API call has gone
away:({https://hbase.apache.org/devapidocs/org/apache/hadoop/hbase/coprocessor/RegionCoprocessorEnvironment.html})?
Sorry if I'm being dense but I don't see a way to get access outside the scope
of the coprocessor to get the handler thread's RPC without
getRegionServerServices()?

Subject: Re: HBase 2.x getRegionServerServices for Client IPAddress Access
Hey Clay!
Looking at branch-2.0, I am seeing RpcServer#getRemoteAddress() or
RpcServer#getRemoteIp() which are static calls that you should be able
to execute in the Master or RegionServer (when running in the context of
an Rpc handler thread, that is.

Hi all,
I've been playing around trying to add client location based ACL controls. (Akin to
the GRANT user@<network specifier> type of access one has in MySQL, et. al.) My
nascent work has been on HBase 1.x but I missed that getRegionServerSerivces went
away in 2.x[1]. Is there a way to now get to the RpcServer for a getRemoteIp() call
from e.g. AccessController now that anyone can think of or should I propose adding a
get remoteIp() method for the coprocessor environments?

[1]: At least that's what I gather by:
* HBase 1.2 RegionCoprocessorEnvironment JavaDocs vs current JavaDocs
* The discussion in and referenced by HBASE-19007
