Kylin.sandbox=true in config

[greg gu]

Hi,
 
I have 4 nodes hadoop cluster, I tried to set  Kylin.sandbox=false in 
kylin.properties, then I started kylin.  but the kylin web site stopped working 
after the change.
 
I use ssh tunneling to visit web site. the url I used is 
http://localhost:7070/kylin
 
before the changes, the above web site works, it shows kylin UI. after I 
changed sandbox to false, the browser says "the web page cannot be found"
 
could you let me know if I need to change Kylin.sandbox to false ?
 
thanks,
Greg
