Jeff Hammerbacher commented on MAPREDUCE-1026:
----------------------------------------------
Hey Owen (and probably Doug),
While we're here: how would this strategy change if map output was transferred
to the reducers using Avro's RPC? Is there authentication in the handshake, and
encryption (ssl?) for the data?
Just trying to educate myself for The Future (tm).
Thanks,
Jeff
