Installation doc should clarify which version of protobuf is required.
Tez installation doc at http://tez.apache.org/install.html says:
> This assumes that you have already installed ... Protocol Buffers (protoc
compiler) 2.5 or later
I initially installed protobuf 2.6.1 ... and mvn failed with:
> [ERROR] Failed to execute goal ... protoc version is 'libprotoc 2.6.1',
expected version is '2.5.0' -> [Help 1]
I observe that pom.xml says:
<protobuf.version>2.5.0</protobuf.version>
At this point, it wasn't clear to me whether I should roll back to protobuf
2.5.0 or override the protobuf.version to be 2.6.1
For newbies like me, it would be helpful to have more clear instructions
regarding protobuf version on the installation page.
Thanks!
