Subject Re: NiFi web interface not starting
Date Mon, 12 Jun 2017 15:19:58 GMT
Hi Matt,

started vis bin/nifi.sh start

Logs do not show anything interesting. Indeed, I see the mentioned lines,
but a curl on http://localhost:9090/nifi returns curl: (52) Empty reply
from server

Bootstrap logs shows:
