What happens when a replica node goes down, with consistency level of quorum?
<p><strong>Scenario:</strong></p>

<ul>
<li>Total Nodes:           3 [ A, B, C ]</li>
<li>Replication factor:    2</li>
<li>Write consistency:     Quorum (2 replicas need to ack)</li>
<li>Read consistency:      Quorum</li>
<li><p>Nodes partion ranges:  </p>

<ul>
<li>A [ primary 1-25,  replica 26-50 ]</li>
<li>B [ primary 26-50, replica 51-75 ]</li>
<li>C [ primary 51-75, replica 1-25  ]</li>
</ul></li>
</ul>

<p><strong>Question:</strong></p>

<p>Suppose I need to insert data 30 and node A is down. What would be the behavior of Cassandra in this situation? Would Cassandra be able to write the data and report success back to the driver (even though the replica node is down and Cassandra needs 2 nodes to acknowledge a write)? </p>
