If you ever try and install RapidMiner on a mac, you might get this little error when starting its engines:
Exception in thread “main” java.lang.UnsupportedClassVersionError: com/rapid_i/LauncherJVMOptionBuilder : Unsupported major.minor version 51.0
To get this error you would have downloaded RapidMiner from their website, unzipped it and clicked on either the RapidMiner Studio app or run the RapidMiner-Studio.sh
In fact you probably did both, as you can only see the error when running RapidMiner-Studio.sh file via terminal, trying to run the app just opens it and then it magically disappears with no error.
So what do you need to do to fix this little problem?
Install java 1.7.x, thats what the error message is saying.
And another suggestion is to install the java 1.7.x jdk rather than jre. It was the only way I could get my mac to pick the latest java version and stop pointing to 1.6.x
Its a data mining we go …….
