Error while running a script step

I have uploaded a huge dataset onto Dataiku and I have tried to concatenate two columns but encountered below error message. How do I troubleshoot this error message?

thank you!

When processing 'ColumnsConcat', the first 118842 rows already used 500 MB

    this means you are working on a too large sample of the input data in your Prepare recipe. You should go in the sampling settings (on the left edge of the screen) and reduce the number of rows. Note that when running the recipe, the full dataset will be used, not just the sample used for designing the steps in the UI
