I had Jupyter Hub installed and running yesterday.
I want to start a new instance - in the case of system maintenance this would be needed - but, after I typed in the same command like yesterday: sudo jupyterhub I got the following messages and off course the instance is not up and running: [I 2018-08-24 13:48:33.066 JupyterHub app:724] Loading cookie_secret from /home/hadoopuser/jupyterhub_cookie_secret [W 2018-08-24 13:48:33.103 JupyterHub app:365] Generating CONFIGPROXY_AUTH_TOKEN. Restarting the Hub will require restarting the proxy. Set CONFIGPROXY_AUTH_TOKEN env or JupyterHub.proxy_auth_token config to avoid this message.
