Never mind. The UI now works fine again, after I restart Storm on the cluster. I still don't know why it could go into that state earlier, and unfortunately nothing in the log file that can help me uncover the mystery.
From: user@storm.apache.org At: 02/17/20 11:19:31To: user@storm.apache.org Subject: page not found error Hi, I don't know what's going on but last week this was working fine. I can open Chrome browser and type dev machine url with port 8080, i.e. http://foobar:8080, and it'll redirect to http://foobar:8080/index.html and showing the Storm UI. However, now I always got error "Page not found" :-( I looked at Storm nimbus.log and ui.log, and didn't see any error. The topology is still running as I see events in the log. Any idea for me on how to troubleshoot this problem? Thanks!
