Dataiku DSS requires an up-to-date license to work.
If you use the Free Edition, the license is automatically generated when you fill out the form the first time you start the product, and never needs updating.
When renewing the license of an existing Dataiku DSS installation, Dataiku provides you with a new file. There are a few ways to update the license with the new file:
Copy your new license file into DATA_DIR/config/license.json
Log into Dataiku DSS, click the “Administration” gear, then click “Enter license” and enter the contents of the license file.
