RapidMiner Set-Up

frey

Hi,

first of all, I am very new to Linux and RapidMiner - so sorry right away.

I try to start RapidMiner and loaded the version of the website.

frey@linux:~$ java --version

java 10.0.2 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

frey@linux:~$ echo $PATH

jdk-install-dir/bin:/home/frey/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-10-oracle/bin:/usr/lib/jvm/java-10-oracle/db/bin

frey@linux:~$ $JAVA_HOME
bash: /usr/lib/jvm/java-10-oracle: Is a directory

frey@linux:~/RapidMiner$ ./RapidMiner-Studio.sh
RAPIDMINER_HOME is not set. Trying the directory '/home/frey/RapidMiner'...

Maybe someone can help me?

I don't understand the PATH variable, is it right?

Your PATH variable shouldn't have jdk-install in it. Usually when you `echo $PATH` it should produce something as follows:

-bash: /usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/user1/.local/bin:/home/user1/bin<br>

So my guess is that you haven't set your PATH properly. It has nothing to do with Rapidminer, that is a linux question. The RAPIDMINER_HOME is also not set, which means it wasn't properly installed. You need to fix the PATH (which would include the the path to java bin) and then re-install Rapidminer.

also please note that RapidMiner does not support Java 10. You must have Java 8 to run it.

This one had me baffled until I actually read the install instructions and saw that Java 8 was supported.
