Vinod Kumar Vavilapalli commented on GIRAPH-37:
-----------------------------------------------
Have you thought about security? In the README, I found that Giraph works with
a secure hadoop installation. I checked the code too (_RPCCommunications_ &
related classes) and figured that on each worker, both the RPC server and the
clients to other peers use Hadoop Mapreduce JobToken for authentication of
connections. If security is a strong requirement for some folks (Y! ?), you
should also think about that when you replace Hadoop RPC with Netty based
solution.

> GIRAPH-12 considered replacing the current Hadoop based rpc method with
> Netty, but didn't went in another direction. I think there is still value in
> this approach, and will also look at Finagle.
