Well, Thrift serves two purposes for us. It manages the RPC API and

Hit the nail on the head. It's nice because it does solve formatting the
data in a compatible way and also delivering that data from client ot
server. It also has lots of nice things like SSL and SASl support baked
in too. Take a look at the 2k lines of code HBase maintains just to set
up an RPC connection. :)
Long term, I'd like to look at Netty for handling the API (because it
seems stable, widely used, and feature-rich). I'm not particularly
concerned about the serialization, as long as the library is stable.
Avro makes as much sense to me as any other, but I haven't actually
used it yet, so I'll reserve judgment.
Even if we move away from Thrift in the long-term for the
client/server and server/server RPCs, we'll probably not get rid of it
entirely. It's still pretty useful for the accumulo-proxy. However,
since that's a small, optional add-on, it'd be pretty easy to isolate
thrift to just be a dependency of that... and presumably it'd be easy
to rebuild that add-on component for different thrift versions or to
support multiple versions.
I know Sean had expressed a desire in trying to pull out Thrift from the
core of things to make this kind of experimentation easier. Being able
to express our RPCs in a way that isn't tied to Thrift would be step #1.
Then, make Thrift be an "implementation" (convert to that generic way
from step #1). After that, it should be straightforward to use whatever
serialization and transport mechanism your heart desires (and your
fingers code).
+1 To Thrift being around in some form for the proxy for the foreseeable
future.

What about the long term future (e.g., Christopher's comment) for Thrift?
Are there particularly attractive alternatives (Avro) that you have in mind
for the project? Asking both as a interested user and general technologist.
