So, you created a brand-new RPC framework? Is there a reason you took this approach over trying out something like Thrift? Thrift is binary and probably lighter weight than the original Hadoop IPC. It also has the advantage of (maybe) being easier to add on to as the RPC interface grows.

            Priority: Minor
             Fix For: 0.16.0


A custom RPC that passes codes representing class names instead of class-as-String saves passing plus encoding/decoding classname Strings; it makes the PerformanceEvaluation sequentialWrites test almost 3 times faster and random reads > 30% faster.
