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.
