title: Cassandra CCM Error: "ccmlib.common.ArgumentError"
body: <p>I installed CCM utility of Cassandra, but when I try to create a cluster with the following command:</p>
  
  <p><code>root@ubuntu2:~# ccm create cluster1 -v=2.0.9</code></p>
  
  <p>I get the following error:</p>

  <strong>ccmlib.common.ArgumentError: Invalid version =2.0.9 (underlying error is: HTTP Error 404: Not Found)</strong></p>
  
  <p>Changing to any other version of Cassandra in the command does not help.
  There is no issue with Internet connection.</p>
  
  <p>Will appreciate help.</p>
