> Vastly improves HBCK performance. Although we are parallelizing getRegionAssignment()
calls, getHRegionConnection()
> gets a big lock. Cache misses can be expensive on heavily-loaded servers because they
need to setup a proxy connection. This hurts cache hits on a cache miss & serializes all
cache misses. We should parallelize both situations.
