Cross-posting to the dev list.

Igor R., is this something that has to be fixed for 1.8 as well? The community is planning
to send the new release for vote by the end of Friday, could you look into this issue by that
time?

this is due to a refactoring performed on the code which did not propagates through the examples,
or simply I used a different version of the documentation in contrast with the one I was running.

I've tried also the docker image, adding my configuration xml files to it, and running the

Anyway, I cannot get it work. Ignite still cannot find the required classes, this time org.apache.ignite.cache.store.cassandra.utils.datasource.DataSource.
The class is indeed located in the jar ignite-cassandra-1.7.0.jar in IGNITE_HOME/modules/cassandra/target.
I tried adding the path to USER_LIBS and CLASSPATH, no different behavior. Maybe the environment
variables got ignored?

If you want to use it you should build Ignite from source code. Such way, it will create ignite-cassandra-tests-${project.version}.zip
where jar may find jar file containing all the test classes.

I get the same for the next class. I tried adding the path to the jar ignite-cassandra-1.7.0.jar
to both CLASSPATH and USER_LIBS, still not getting found. Opening the jar I cannot find the
requested class. Am I missing some dependencies?
