Andrew Wang commented on HADOOP-13363:
--------------------------------------
Based on my read, proto2 is the default parsing mode, we need to explicitly
opt-in to proto3. This is nice, since we won't have to modify our existing
proto files if we upgrade PB.
I think the mode also only affects parsing of the .proto file. proto3 adds new
types like maps and unions, which aren't available in proto2 mode. I think
enums are also different.
> Upgrade protobuf from 2.5.0 to something newer

> Standard protobuf 2.5.0 does not work properly on many platforms. (See, for
> example, https://gist.github.com/BennettSmith/7111094 ). In order for us to
> avoid crazy work arounds in the build environment and the fact that 2.5.0 is
> starting to slowly disappear as a standard install-able package for even
> Linux/x86, we need to either upgrade or self bundle or something else.
