title: Cassandra_NotFound Exception when trying to instantiate a column_family object from phpcassa
body: <p>I have setup a Cassandra instance 0.7 in my Windows 7 machine (64bit) .</p>
  
  <p>The cassandra server is up and running and it is successfully listening to thrift clients. I have tested the instance by successfully creating my own sample keyspace and column family .</p>
  
  <p>Now , I have to connect to this Cassandra instance from my PHP script . I tried using <strong>thobbs\phpcassa</strong> . </p>
  
  <p>Here I ran into trouble . In the installation it's mentioned the steps for <strong>'make,build'</strong> for UNIX/Linux system but nothing is mentioned for Windows .</p>
  
  <p>Knowing not what to do next , I tried to copy the phpcassa folder inside my htdocs folder (of apache) and created a test file cassandra_test.php with the following content:</p>
  
  <pre><code>&lt;?php
  ini_set('display_errors',1);
  require_once('phpcassa/connection.php');
  require_once('phpcassa/columnfamily.php');
  
  $servers = array("localhost:9160");
  $pool = new ConnectionPool("demo", $servers);
  
  $column_family = new ColumnFamily($pool, 'user');
  
  
  ?&gt;
  </code></pre>
  
  <p><strong>demo</strong> is the sample keyspace that I have created from the command prompt . Also , I have created a sample column_family <strong>user</strong> in my demo keyspace.</p>
  
  <p>Executing this script in my browser gives me the following exception:</p>
  
  <pre><code>Fatal error: Uncaught exception 'cassandra_NotFoundException' in C:\Program Files   (x86)\Apache Software Foundation\Apache2.2\htdocs\phpcassa\columnfamily.php:198 
  Stack trace: #0 C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\cassandra_test.php(10): 
  ColumnFamily-&gt;__construct(Object(ConnectionPool), 'user') #1 {main} thrown in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\phpcassa\columnfamily.php
  on line 198 
  </code></pre>
  
  <p>I think phpcassa can't find my local cassandra instance . How to check that ?</p>
  
  <p>Also </p>
  
  <pre><code>$pool = new ConnectionPool("demo", $servers);
  </code></pre>
  
  <p>didn't gave any error/warning . So , I am entirely not sure what's the root cause for this exception? 
  I am a newbie for cassandra and PHPcassa .Really sorry if this problem sounded pretty trivial.</p>
