Subject Re: Tool for interactive fault injection testing
Date Mon, 02 Jul 2012 20:14:38 GMT
I was unable to find any issues so far. It seems like ZooKeeper does a
great job at
handling network failures.

This tool is deploying a ZooKeeper cluster on a cloud provider using Whirr
together
with Byteman [1]  (attached to the JVM).

Faults are injected by using Byteman rules. See this tutorial:
https://community.jboss.org/wiki/FaultInjectionTestingWithByteman#what_is_fault_injection_testing

I am planning to improve the tool to have the ability o inject arbitrary
rules through the web UI.

As an workload generator I am using a distributed queue implementation
that's handling
ConnectionLoss by retrying to post the message (duplicates are acceptable
when measuring the latency).
