> System tests against multiple nodes
> -----------------------------------
>
> Key: CASSANDRA-874
> URL: https://issues.apache.org/jira/browse/CASSANDRA-874
> Project: Cassandra
> Issue Type: Test
> Components: Tools
> Reporter: Jonathan Ellis
>
> We have a system test suite (see
> http://wiki.apache.org/cassandra/HowToContribute ) but it only runs against
> the local machine, which is suboptimal even if we didn't have a bunch of
> optimizations to make writes to a local node skip most of the messaging layer.
> We'd like to automate testing against a whole cluster. Paul has some code
> using libcloud to do stress tests against an ephemeral rackspace cloud
> servers cluster at http://github.com/pquerna/ccb, which is probably useful as
> a starting point, but rather than running stress.py you'd want to put
> together a more comprehensive suite, based on the existing system tests but
> also explicitly covering things like range queries that span multiple nodes
> and failure conditions like Hinted Handoff (see
> http://wiki.apache.org/cassandra/HintedHandoff ) and repair
> (http://wiki.apache.org/cassandra/ArchitectureAntiEntropy ) resulting from
> deliberately disabling a node temporarily.
> Adding tests for ops tasks like http://wiki.apache.org/cassandra/Operations
> would be awesome too.
> Finally, CASSANDRA-561 might make something like this possible using a
> simulator instead of hardware-level virtualization, which would be both more
> convenient and less expensive. But someone just dumped a huge zip in our
> laps w/o really trying to collaborate with us there, so if you want to try to
> resurrect that code or otherwise go that route, be more open about what
> you're doing. :)
