Hello,
I'm trying to get the web_ui to use the --advertise_ip to connect to master's instead of the --hostname passed into the slaves. running mesos 28 slaves run with a command like this: mesos-slave --master=zk://xxx/mesos --advertise_ip=y.y.y.y --containerizers=docker,mesos --hostname=tmp-mesos-slave-1 --ip=10.240.0.6 So when you hit sandbox, it connects to the --hostname. Background: I had been using ip (public) for --hostname which worked well for my framework, but when launching spark on mesos, it requires the internal ip for it to work on GCE. Thanks!
