body: <p><strong>How to copy a columnfamily from one cassandra cluster to another?</strong></p>
  
  <p><strong>Scenario:</strong></p>
  
  <ol>
  <li>I have only host's IP(for both source and target clusters), port, key_space name and column_family name.</li>
  <li>I already created metadata in target cluster(only data needs to be copy).</li>
  <li><strong>Most preferentially</strong>,I want this to be done in single/multiple spark jobs(creating DataFrame intermediately and then saving it) using spark-cassandra connector JAVA API.</li>
  <li><strong>Moderate preferentially</strong>, using cassandra-java driver from datastax. </li>
  <li><strong>Least preferentially</strong>, using cassandra-jdbc driver and spark-cassandra connector JAVA API.</li>
  </ol>
  
  <p>Any help will be appreciated.Thanks in advance.</p>
