title: Cassandra client is not showing changes made through json2sstable
body: <p>I have converted sstable to Json file using Cassandra sstable2json utility and then modified some row values, now i invoked the utility json2sstable.The Utlity json2sstable executed successfully using following command.</p>
  
  <p>command:</p>
  
  <pre><code>bin/json2sstable -s -K UserDemo -c Users Users.json /opt/dse-2.1/dse-data/UserDemo/Users-hd-1-Data.db
  </code></pre>
  
  <p>I tried to see the changes are reflected or not using cassandra client. Noticed that changes are not reflected what i did using json2sstable utility.</p>
  
  <p>and I tried to refresh the CF Users using nodetool but no changes noticed.</p>
  
  <p>Please advice on what could be the reason for not reflecting in the cassandra.</p>
  
  <p>Advance thanks.</p>
