Daryn Sharp updated HADOOP-9421:
--------------------------------
Attachment: HADOOP-9421.patch
I scaled back my patch to the simplest skeleton implementation. The highlights
are:
* SASL is very stateful
* SASL is wrapped with RPC header like normal requests to facility dynamic
decoding
* Client can correctly handle RPC exceptions during SASL negotiation
* Server advertises SASL mechs to client
Deficiencies to be addressed in another jira:
* RPC client still pre-instantiates a SASL client and blindly uses it - instead
of using the server advertisement
* RPC server is also pre-creating a SASL server
* Protocol and serverId not included in the SASL mech advertisement or the
client initiate
Code cleanups:
* RPC client loop for SASL and normal operation should be folded together
simplify and reduce redundant code
* RPC server decoding paths for connect/sasl/rpc can be greatly simplified -
the existing impl is already a twisty maze
I've started on some of the cleanup, but I wanted to get a functional patch to
unblock the start of v9 testing, and that I can use as a base for work of a
larger scope.
