Tsz Wo (Nicholas), SZE commented on HADOOP-2184:
------------------------------------------------
> Should we edit the description to reflect this?
The description does not say that (1) and (3) are included. I would like to
emphasize "Allow pluggable security implementations". So (1) and (3) is
indeed provided by the pluggable security implementation, not this framework.
BTW, could you propose a new description if there is anything not clear?
> Change RPC to provide secure communication
> ------------------------------------------
>
> Key: HADOOP-2184
> URL: https://issues.apache.org/jira/browse/HADOOP-2184
> Project: Hadoop
> Issue Type: New Feature
> Components: ipc
> Affects Versions: 0.15.0
> Reporter: Tsz Wo (Nicholas), SZE
> Assignee: Raghu Angadi
> Fix For: 0.16.0
>
>
> In the current version of RPC, there is no authentication or data protection.
> We propose to change the RPC framework, so that secure communication is
> possible.
> The new RPC should:
> - Compatible with current RPC
> - Allow a pluggable security implementations (see HADOOP-1701)
> - Support both secure and non-secure modes.
> Here is a rough idea:
> - Store security information (e.g. username, keys) in a ticket
> - Use the ticket to establish a RPC connection
> - Create secure sockets by the (subclass of) SocketFactory corresponding to
> the selected security implementations
> - Send the data and RPC parameters with the secure sockets
> When authentication is supported, the RPC callee should also initialize
> caller information during RPC setup and execute the RPC on the caller's
> behalf.
