Subject [jira] [Commented] (GIRAPH-37) Implement Netty-backed rpc solution
Date Sun, 18 Sep 2011 11:58:08 GMT


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.
