<p>Assume a Cassandra cluster with hosts <code>A</code> and <code>B</code>. This cluster shall now be extended with another host <code>C</code>. Assume that <code>C</code>is on a firewalled network were all packets are dropped by default.</p> <p>Which ports and protocols must be opened up between <code>C <> A</code> and <code>C <> B</code> for the new node <code>C</code> to function properly?</p>
