title: Cassandra not working when one of the nodes is down
body: <p>I have a development cassandra cluster of two cassandra nodes [Let's call them NodeA and NodeB]. I also have a script that is continuously sending data on NodeA. I have created the database with the following parameters:</p>
  
  <pre><code>CREATE KEYSPACE test_database WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '1'}  AND durable_writes = true;
  </code></pre>
  
  <p>Now, for some reason NodeB is stoping after some time. But the issue is, as soon as NodeB stops, the script that is sending data to NodeA starts giving data insertion error.</p>
  
  <p>Can anyone point out a probable reason for the same.</p>
  
  <p>Update: Both the nodes are seed nodes.</p>
