[ERROR] Failed to execute goal

on project hadoop-common: org.apache.maven.plugin.MojoExecutionException:
protoc version is 'libprotoc 3.0.0', expected version is '2.5.0' -> [Help
1]{code}
this failure is unrelated to this patch. From the output log，it should be
protoc version problem. The protoc version should be 2.5.0.
