Import Data hangs

Hi,

I am using RapidMiner Studio 9.6 Educational Edition in Ubuntu 19.04 box. I am trying to Import Data (Load Data) in RapidMiner repository. The CSV file is having 6 attributes and around 1200 examples. The overall file size is 25kb. The process hangs so that I needed to kill the process to terminate RapidMiner. Any help will be much appreciated. Thanks.

    My colleague @BalazsBarany recommends using Amazon Coretto with all Linux/Ubuntu installations. See this thread for a full discussion: https://community.rapidminer.com/discussion/56326.

    Hi @sgenzer, 
    Thanks for your response. It seems that the problem is fixed now. I did the following:

    Imported the Corretto public key and then add the repository to the system list by using the following commands
     wget -O- https://apt.corretto.aws/corretto.key | sudo apt-key add - 
     sudo add-apt-repository 'deb https://apt.corretto.aws stable main'

    Installed Corretto 8 by running command
     sudo apt-get update; sudo apt-get install -y java-1.8.0-amazon-corretto-jdk

    Ran the following command to verify the installation
    java -version

    Set the JAVA_HOME in /etc/environment

    Also, I would like share with @BalazsBarany that this problem persists in RapidMiner Studio 9.6. Thanks.

    Regards,
    Raj
