How to update an ubuntu 12.x box to protoc 2.5.0 and so build Apache hadoop 2.x+



Deamz @ Mina Road

Here are some working notes on how to push up an Ubuntu 12.x machine to a version of protoc that builds Hadoop. It is a shame that protobuf.jar doesn't include a protoc compiler
Actually it's also a shame that protobuf.jar isn't backwards compatible across versions. I'm
now ooking at Apache Thrift and thinking "maybe I should adopt that in my own code".


Run these as root:
 
cd ~
apt-get -y remove protobuf-compiler
curl -# -O https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz
gunzip protobuf-2.5.0.tar.gz 
tar -xvf protobuf-2.5.0.tar 
cd protobuf-2.5.0
./configure --prefix=/usr
make
make install
protoc --version

Then log in as you and again run

protoc --version

The output of the --version commands must be "libprotoc 2.5.0". Any error; any different version: your build of Hadoop won't.

  1. you don't need to remove the older version. that is not necessary. you can directly go and install the new version. there is no conflict.
