Subject [jira] [Commented] (GIRAPH-211) Add secure authentication to GIRAPH IPC
Date Fri, 29 Jun 2012 16:42:44 GMT


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 :-)

> 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.
