             Summary: [Analytics] Use a classloader to isolate in-jvm dtest classes in integration test
                 Key: CASSANDRA-19528
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-19528
             Project: Cassandra
          Issue Type: Improvement
          Components: Analytics Library
            Reporter: Francisco Guerrero
            Assignee: Francisco Guerrero


We need to isolate the in-jvm dtest classes (coming from the shaded dtest jar) from the classes in Cassandra Analytics when running integration tests. The isolation will allow us to test the Analytics code in the {{AppClassloader}} without any class pollution from classes coming from the shaded dtest jar. In some cases, the pollution can spill to classes that are shaded in the analytics project (metrics, json serialization, guava, etc).

With the isolation in place we can be more confident that the code we are testing is the code that will be running in a Spark environment.
