title: How to match codec in cassandra for list<varchar> <-> java.util.List
body: <p>I have a column <code>info map&lt;text, frozen&lt;list&lt;text&gt;&gt;&gt;</code> in cassandra.
  Trying to retrieve this map data in java from the below code.</p>
  
  <pre><code>for (Row row : conn.getSession().execute("SELECT info FROM demo.variants where chr = '" +chr + "' and pos = " + pos)) {
      Map&lt;String, List&gt; map = row.getMap("info", String.class, List.class);
      System.out.println(map);
  }
  </code></pre>
  
  <p>When doing this way, I am getting the error</p>
  
  <pre><code>com.datastax.driver.core.exceptions.CodecNotFoundException: Codec not found for requested operation: [list&lt;varchar&gt; &lt;-&gt; java.util.List]
  </code></pre>
  
  <p>I could not figure out how to resolve this nested type codec exception. What are the ways to resolve this?</p>
