> I have two CDH clusters (stage and prod) with the same environment, the same Livy service installed on them, a Python 3.7 environment configured via Ansible, and I write PySpark by calling Livy via sparkmagic in jupyter-lab. code in jupyter-lab, the stage environment works fine, but the prod environment gives an error.
