---------------------------------------
You might want to take a look at this -- https://github.com/jmhsieh/gremlins
it is a fork of work that Todd Lipcon did a while back that does some of what
you are talking about.
> Add a script to simulate a dead machine during the integration tests

> Key: HBASE-7839
> URL: https://issues.apache.org/jira/browse/HBASE-7839
> Project: HBase
> Issue Type: New Feature
> Components: test
> Affects Versions: 0.96.0
> Reporter: nkeywal
> Assignee: nkeywal
> Priority: Minor
> Fix For: 0.96.0

>
> 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.
