Todd Lipcon commented on HADOOP-9151:
-------------------------------------
bq. Todd, not sure what you mean here. From what I know 0.23.x does not have
any of the protobuf changes or all the other changes that have happened in ipc
right?
Sorry, my mistake.
Still, 2.x has been out for quite some time now, and I don't think it's a good
idea to break compatibility for what amounts to a surface-level cleanup.
Despite the "alpha" label, there are a lot of people using it, and breaking the
compat should require a really good reason.
Certainly it's a shame to have some non-PB items in there, but they're very
simple serializations of strings. I've implemented a simple client for it in
C++ and it wasn't at all difficult to deal with the few places where writables
snuck into the header.
