> There's a backdoor CoprocessorHConnection used to ensure that a batched
> mutation does not go over the wire and back, but executes immediately
> locally. This is leveraged by Phoenix during secondary index maintenance (for
> an ~20% perf improvement). It looks to me like it's no longer used, as the
> following function is never invoked:
> public
> org.apache.hadoop.hbase.protobuf.generated.ClientProtos.ClientService.BlockingInterface
> getClient(ServerName serverName) throws IOException {
> It'd be good if feasible to add an HBase unit test to prevent further
> regressions. For more info, see PHOENIX-1166.
