Note: this is a stub…
One important page is: https://github.com/knime-ip/knip-sdk-setup
The readme there is essential.
Recently we ran a very intense training procedure from within a KNIME workflow. The whole thing ran for roughly 4 days.
Finally terminated we ran into troubles saving the workflow, getting some ‘File access problems: /var/folders… etc. etc’ error dialog.
Turns out that Java cleans up its temp folder after 3 days or so (on MacOS at least). In doing so KNIME ended up having the open workflow being corrupted.
Way out: before starting such a monstrous run you might want to configure KNIME to use another temp folder… one that Java does not wipe out every now and then.
