Hi,
I am testing the Cassandra connector and I may have found a bug using
CassandraSink-DSL. During the execution it throws
`java.io.NotSerializableException:
org.apache.flink.streaming.connectors.cassandra.CassandraSink$CassandraTupleSinkBuilder`
CassandraSinkBuilder doesn't implement java.io.Serializable. I forked and
added java.io.serializable to CassandraSinkBuilder, after that it throws
`java.io.NotSerializableException:
org.apache.flink.streaming.api.datastream.SingleOutputStreamOperator`.
Not using the DSL it works as expected.

Hope it helps.
> Add a connector for streaming data into Cassandra

> Key: FLINK-3311
> URL: https://issues.apache.org/jira/browse/FLINK-3311
> Project: Flink
> Issue Type: New Feature
> Components: Streaming Connectors
> Reporter: Robert Metzger
> Assignee: Andrea Sella
>
> We had users in the past asking for a Flink+Cassandra integration.
> It seems that there is a well-developed java client for connecting into
> Cassandra: https://github.com/datastax/java-driver (ASL 2.0)
> There are also tutorials out there on how to start a local cassandra instance
> (for the tests):
> http://prettyprint.me/prettyprint.me/2010/02/14/running-cassandra-as-an-embedded-service/index.html
> For the data types, I think we should support TupleX types, and map standard
> java types to the respective cassandra types.
> In addition, it seems that there is a object mapper from datastax to store
> POJOs in Cassandra (there are annotations for defining the primary key and
> types)
