Thank you for review.

I think that the GraphGenerator is necessary to test the overall of IO-related 
sub systems. For example, *InputFormat and Partitioners can be examined by some 
generated data set instead of PseudoRandomVertexInputFormat.

As you mentioned, I modified PageRank/RandomMessageBenchmark to use a specified 
InputFormat and an input path. If the input format and input path are not 
given, they will work as the current implementation using

> To provide users with benchmark environments and to deeply test the
