stack commented on HADOOP-13363:
--------------------------------

Perhaps this pom helps? 
https://github.com/apache/hbase/blob/master/hbase-protocol-shaded/pom.xml Its 
the hackery from hbase generating shaded pb module inline w/ main build. PB 
files are generated on the fly using the godsend protobuf-maven-plugin plugin 
which pulls the appropriate protoc at build time (so no need to set up a protoc 
or protoc path). The replacer plugin rewrites generated pbs so shaded and in 
place for downstream modules at build time. I remember getting ordering and 
shading correct was a pain but have forgotten the details unfortunately.

> 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.
