on sandbox kafka broker is binding to the ip of the VM. You can either
use the hostname (sandbox.hortonworks.com) or ip of the sandbox 

 netstat -anp | grep 6667
tcp        0      0 ::ffff:10.0.2.15:6667       :::*                    
   LISTEN      9485/java           
tcp        0      0 ::ffff:10.0.2.15:6667       ::ffff:10.0.2.15:59883  
   ESTABLISHED 9485/java
