title: how to integrate cassandra with zookeeper to support transactions
body: <p>I have a Cassandra cluster and Zookeeper server installed. Now I want to support transactions in cassandra using zookeeper. How do i do that. </p>
  
  <p>Zookeeper creates znodes to perform read and write operations and data to and fro goes through znodes in Zookeeper. I want to know that how to support rollback and commit feature in cassandra using Zookeeper. Is there any way by which we can specify cassandra configurations in zookeeper or zookeeper configurations in cassandra.</p>
  
  <p>I know cassandra and zookeeper individually how data is read and written but I dont know how to integrate both of them using Java.</p>
  
  <p>how can we do transactions in Cassandra using Zookeeper.</p>
  
  <p>Thanks.</p>
