Subject [jira] Created: (HADOOP-2182) Change RPC to provide secure communication

Change RPC to provide secure communication

                 Key: HADOOP-2182
                 URL: https://issues.apache.org/jira/browse/HADOOP-2182
             Project: Hadoop
          Issue Type: New Feature
            Reporter: Tsz Wo (Nicholas), SZE

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
- 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.
