Does it make sense for these methods to exist down the road though to ease testing of ThriftClientHandler by itself? Or do you think TabletServer and ThriftClientHandler shouldn't need to be tested in isolation? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
