Vinayakumar B commented on HADOOP-13363:
----------------------------------------
{quote}So, a safer way for the ecosystem I came up with is as follows:
1. Shading updated protobuf version e.g. protobuf v3.
2. Gradually replacing existent parts where protobuf v2.5 is used with protobuf
v3. This can be done on a non-master branch. Here, we remain the dependency on
protobuf v 2.5. This is because other projects may use it.
3. Announcing when to delete the dependency.
4. Removing the dependency on the future version.
This kind of gradual replacing approach might be acceptable by the Hadoop
ecosystem, I think.

I think, this should be fine if it works.. Specifically #1 and #2.
[~ozawa], Have you verified this already?

> 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.
