> With the default configuration passed to a RegionCoprocessor environment, you cannot reach an HTable on the same cluster (at least in 0.94 - no verified yet in 0.96/8). The reason is in the usage of CompoundConfiguration (backported to 0.94 in HBASE-8176) when loading a table coprocessor we just do (RegionCoprocessorHost, ln 182):
> {code}
> Configuration newConf = new Configuration(conf);
> // set per-table cfspec properties
> {code}
> but the conf we pass in a CompoundConfiguration, which means the copy constructor from Configuration doesn't work at all. 
> So, we really need two things:
>  1. A test that we can reach another HTable in the same cluster via a coprocessor by default
>  2. Fixing the configuration creation in RegionCoprocessorHost to support (1)
