title: What is the port number for cassandra and solr?
body: <p>I read the <a href="http://www.datastax.com/documentation/opscenter/4.0/opsc/reference/opscPorts_r.html" rel="nofollow">documentation</a> which says <code>7199</code> is <code>JMX port number</code> and <code>8983</code> is <code>solr port number</code> and <code>9160</code> is <code>cassandra client port number</code>. But if i start</p>
  
  <pre><code>  dse cassandra -s
  </code></pre>
  
  <p>starts solr. If i start cassandra-client in the same machine</p>
  
  <pre><code>  dse cassandra -f
  </code></pre>
  
  <p>It says</p>
  
  <pre><code>    Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 7199; nested exception is:
      java.net.BindException: Address already in use
  </code></pre>
  
  <p>So I understand that both tries to use same JMX port number. </p>
  
  <p>Is there any way to specify two port numbers one for solr or one for cassandra OR is there any way to start both in the same machine.</p>
  
  <p>I am using datastax 2.2.2 tarball set up.</p>
  
  <p>Any ideas?</p>
