actually, I think we do not need to rename the graphar to incubator-graphar, since the https://github.com/apache/graphar would redirect to https://github.com/apache/incubator-graphar, we just need to rename that links that can not been redirected.

Oh, I see what you mean, I'm going to recheck and I will rename the links that can not been redirected.
