Integration of Elasticsearch2.3.0 with cassandra 3.0.4

Hi team,

I am able to pull the data already done with older versions of ES 1.4.5 and Cassandra 2.1.3 using river but the requirement changed to use the latest versions . I am in bit confusion how to start.

Could you please suggest (help) me how to integrate the latest versions of elasticsearch 2.3.0 with cassandra 3.0.4 (as river is depricated from 2.0).

Thanks in advance....
