Nicolas Liochon resolved HBASE-7839.
------------------------------------
Resolution: Won't Fix
In HBASE-7840, the solution relies on a passwordless sudo. It's more secure.

> A kill -9 cannot be used to simulate a dead box. With a kill -9:
> 1) the sockets are closed by the OS
> 2) the next calls will get immediately a connection refused.
> Physically unplugging the cable does work.
> To automate this, the best solution seems to be using a firewall config.
> It's a little bit complicated however, because we need to refuse the incoming
> packets. If we block the out connection, it's detected by the OS and there is
> no wait on the socket.
> Moreover you need to be root, or use a program with a sticky bit to launch
> the script that changes the firewall config.
> This will be usable from the integration tests.
