Maja Kabiljo commented on GIRAPH-211:
-------------------------------------
I'm not sure what am I supposed to do here. My first understanding was that we
want all the messages which go through the system to be protected. In that case
I can't see how workers can find out about tokens of others. I guess RPC
authentication is implemented in hadoop, since the only thing I see in RPC
classes in Giraph is the part when the job checks whether it has privileges to
make a connection. I need a bit more information here, or I can reassign the
task if someone finds it easier to do it than to explain it :-)

> 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.
