Yes, you must also specify hadoop version or else you would be using 0.23.x artifacts with version 1.0.4 where they don't exist. The most recent 0.23.x build is not "0.23" but "0.23.4". (Use 0.23.3, if that hasn't made it to the repo yet.)
0.20.2 is quite old, older than 1.0.4. I thought you wanted the 0.23.x / 2.0.x line? I wouldn't recommend you use 0.23.x but that's how you would try to.
