Issue found:
Hi I have a computer which does not have internet connection and I wanted to
used Pinot to analyse data generated on it and found there is uncaught
exception which is caused by internet liveness check implemented in NetUtils:41.
The exception is mentioned everywhere but never caught and handled.
All other components when started through pinot-server.sh like controller,
broker and zookeeper, they had to be given host config to avoid this problem
there. But in this server start it is somewhere able to go through hoops and
call internet.
It did not take `-serverHost` as before server something else tries to
perform NetUtils:41.
How to replicate:
1. Disconnect the computer from internet for real.
2. Try starting the server or any other component without any parameter like
Controller, Zookeeper, Broker, etc.
3. It should try connect to internet to determine it is offline.
4. And exit with stacktrace because it cannot connect to internet.
Here is a stack trace:
