Parallel execution causes RuntimeException

Hi everyone,

 

I installed the Time Series extension (v. 0.2.002) and I ran the Forecast Validation of ARIMA Model for Lake Huron template successfully.

 

Afterwards I installed the Series Extension Version (v. 7.4.0) to experiment with the "Autocorrelation Transformation Operator" as suggested in this RM post. After that, every time I run a process with Forecast Validation operator, I get the following error:

 

Exception: java.lang.RuntimeException
Message: Could not prepare concurrent execution of operator Forecast Validation.

When I set the enable parallel execution to false, the process is executed successfully.

 

This problem also happens sometimes in the regular Validation operator as well.

I tried reinstalling the extensions, as well as RapidMiner itself in a clean repository but still the problem remains.

 

I can live without parallel execution although it speeds things up considerably so any help is highly appreciated!

    Hi,

     

    This looks like a bug to me. If you have parallel execution I guess you also have access to support.rapidminer.com, right?

     

    Can you write a ticket including process, data and logs?

     

    Regards,

    Sebastian

    @imarkou so you contacted RM Support directly? If so, I will delete this thread. Let me know.

    @sgenzer Yes, I opened a case.
