Question Regarding Using H2O Extension on KNIME Hub

KNIME Extensions
1

Hello KNIME Support Team,

I have a question regarding the use of the H2O Extension.

On a personal local PC, when using H2O, data is converted to the H2O format using the H2O Local Context node (the triangular port).

If we want to upload a workflow to the KNIME Hub and execute it there instead of on a local PC, should we still use the H2O Local Context node?
Or is there a different node or approach required for running H2O on KNIME Hub?

We are planning to use H2O with the free (non-commercial) version, not a paid license.

Thank you in advance for your support.

@JaeHwanChoi Yes, your approach is correct. The H2O Local Context node will work on the KNIME Hub just as it does on your local machine.

In this context, ‘Local’ means that the H2O instance runs within the same environment (the executor) as the workflow. Since you are using the H2O extension integrated with KNIME, this works with the free version and does not require a separate H2O license or a remote cluster setup.
