The problem is that the cassandra jar currently contains 2 shaded guavas.
I already have a fix ready that suppressed the root-poms shade plugin configuration inside the cassandra submit.

I will submit that next week.

Hey everyone,

I'm having an issue using the Flink -> Cassandra connector. The error message I get is:

*Class com.datastax.driver.core.DefaultResultSetFuture does not implement the requested interface org.apache.flink.shaded.com.google.common.util.concurrent.ListenableFuture

*
I believe the problem is related to this (https://github.com/apache/flink/pull/2133) pull request but it still results in this error. Does anyone have any advice on how to debug it?

Thanks,
Eamon
