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.

> Gianmarco De Francisci Morales asked on the user list:
> bq. I am getting the exception in the subject when running my giraph program
> bq. on a cluster with Kerberos authentication.
> 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.
