Description

If protoc fails with a compilation error in the proto files, our Maven plugin won't print the details. The only way to figure it out is to repeat running the protoc command manually from outside the Hadoop build. This is because our ProtocMojo only captures stdout from the protoc command, and compilation errors get written to stderr.
