Thanks Matt, the below is when I browsed to loca nifi url. In the last working
session of nifi, I was configuring an ExecuteSql processor before it blue-d
screen. Could it have got into a bad state? How do I get out of it?
Thanks,
Keith

Keith,
Were there any errors in any of the log's (nifi-app.log or nifi-user.log)
before shutdown or during start up. I'm not 100% sure what version your running
but it appears it's having trouble loading the Anonymous user. This user is
created during startup, stored in the users database, and should always be
available. Any additional errors or details would be helpful. Thanks.

I can do the long route or cleaning up the nifi folder and rebuilding it, but
want to know if there is a surgical way to remove this issue.
Thanks,
