Couls not find how we can use the big data processing

I’m using the open source model of KNIME , but I’m unable to find to figure out how can we configure that on the application level .

Could you provide more detail about what you’re trying to do and what problems you’re encountering?

I want to offload spark jobs to a remote cluster to extract and do the processing job

See if this helps:
