    Hi Michel,

     

    it is unlikely that the address is localhost, unless you install RapidMiner on the VM itself.

     

    Can you check either the Cloudera Quickstart VM or the Cloudera Hadoop CDH 5.x guides at https://docs.rapidminer.com/radoop/installation/distribution-notes.html depending on your cluster type?

     

    Best,

    Hi Peter,

     

     

    I understand that the Master Adress is incorrect. How do I find the correct Master Adress?

    Hi Michel,

     

    I recommend to use te "Import from Cluster Manager" option to create the connection. You can specify the Cloudera Manager URL and credentials and the connection will be created, you only need to specify a couple of settings.

     

    May I ask if this is a quickstart VM or a larger cluster?

    Hi Peter,

    Thanks for your answer.

    I'm working on an opportunity with a financial
    services client. The customer is looking for help with sentiment analysis and data
    source is Cloudera.    The idea would be to propose using RapidMiner
    RAdoop on top of the Hadoop cluster for the analysis.

    My goal in this prospect is to implement a ML model in RM, but I have at least to show to the customer how to connect with Cloudera data. 

    I'm an Ambassador for RM, but my expertise is on Machine Learning and know very little about Hadoop.

    Although I believe I can show how to work with RAdoop, I can't connect.

    I also don't know how to specify the Cloudera Manager URL and credentials.

     

     

    Regards,

     

    Michel
