Sanjay Radia commented on HADOOP-7524:
--------------------------------------
Attached patch allows the server to support multiple protocols including
multiple versions of the same protocol.
* Server can add additional protocols and protocolImpls to a rpc server using
#RPC.addProtocol
* Server side keeps a list of protocols and versions
* Can add an annotation to a protocol to give its protocol name (default is the
class name as before) this
allows one to use different classes to implement different versions of the same
protocol.
* Better support for Mixins (call now contains the declaring class along with
method name).
* Inherited interfaces automatically added (this allows compatibility with old
usage and also allows mixins)
* See ipc/TestMulitpleProtocolServer for examples
> Change RPC to allow multiple protocols including multuple versions of the
> same protocol
