Hi
I have written a java web app which queries a Druid DB via the Remote
driver, it all works fine on my dev machine, but after installing the app on
my test machine I get the error below. Druid is up and working fine.
It must be a configuration issue, but I can't find it.
Any help appreciated, thanks a lot
Francesco
