[SOLVED] Rapidminer 5.3 on Linux

spok2

Dear all,

many thanks in advance for a hint what might be wrong ...

I use a text mining process on Windows, consisting of

- Process documents from files
-- Tokenize
-- Filter Stopwords
-- Stem (Porter)
-- Filter Tokens by Length
-- Transform Cases

with no problems.

Now I tried to copy the process to Ubuntu 14.04

- either by copying the *.rpm file
- or by newly creating the process on ubuntu

To my opinion both processes are identical; both tell me: "No problems found"

Starting the process on Windows I get results after about 2 minutes (Wordlist and Example Set)
Starting the process on Ubuntu I get an emty result after 0 seconds (Wordlist as well as Example set are both empty); process stops without errors.

What might go wrong?

Hi,

my bet would be some encoding issue. Check your process XML for weird symbols.

Marco,

thanks, but this is not the problem.

What I did (System: Ubuntu 14.04 with Oracle Java 1.8.0_31):
- completely deleted rapidminer, including .RapidMiner5 in $HOME
- downloaded rapidminer 5.3.13 from Sourceforge
- unzip below my local homedir
- set all dirs to 755, all files to 644
- copied 5 arbitrary english articles from the web and put them in a directory
- copied RapidMinerGUI from scripts to installation dir
- started rapidminer
- made update to 5.3.15
- installed extensions
- created a new process, consisting of the elements I already mentioned (xml see below)
- get no errors, as well as no results after running the process, ready within 0s

Same process runs on Windows 7 without any problem

Hi,

there is one difference which might be responsible: On Linux, you're using your local Java installation, i.e. Java 8 in your case. On Windows, a JRE is shipped with RapidMiner, so you're using a Java 7 version there. You might want to try again on Linux with Java 7.

Regards,
Marco

Marco,

thanks, thatś it ...

I removed Oracle Java8, installed Oracle Java7 and all is fine.

Best regards
