Brandon Li commented on HADOOP-8736:
------------------------------------

{quote}build() method, please follow the coding guidelines and have {} after 
if.{quote}
done
{quote}Throwing HadoopIllegalArgumentException is fine. But if you are doing 
that for two of the parameters, I suggest doing the same for handlerCount and 
conf parameter as well.{quote}
Done for conf, handlerCount has a default as "1".
{quote} In javadoc for build() method please add @throws and say if mandator 
fields are not set, the build method will throw 
HadoopIllegalArgumentException.{quote}
Done.
{quote} Please add a testcase where you create RPC server without mandatory 
fields and ensure exceptions are thrown. We could perhaps add this to 
TestIPC.{quote}
Done in TestRPC.java.

> There are quite a few variants of getServer() method to create an RPC server. 
> Create a builder class to abstract the building steps and avoid more 
> getServer() variants in the future.
