Subject [jira] [Commented] (GIRAPH-211) Add secure authentication to GIRAPH IPC
Date Fri, 20 Jul 2012 01:01:51 GMT


Eugene Koontz commented on GIRAPH-211:

I am working on a patch for this after studying both the Hadoop RPC side and the Netty side
of things. I'm posting a proposal, but, since it's long, I'll attach it as a .txt. But to
get the discussion started, I want to describe the idea briefly: it uses the Job Token as
a SASL credential so that one BSPWorker can authenticate itself as a client to another BSPWorker
acting as a server. This is what is going on with Hadoop RPC, so we just need to replicate
this behavior in the Netty implementation.

> This leads to the idea of having Kerberos authentication supported within GIRAPH. Hopefully
it would use our fast GIRAPH-37 IPC, but could also interoperate with Hadoop security.
