title: Inserting Data into Cassandra using hector
body: <p>I'm trying to insert data into cassandra data base using hector api. The code that I have used is displayed below. </p>
  
  <pre><code>&lt;i&gt;
  import me.prettyprint.cassandra.serializers.StringSerializer;
  import me.prettyprint.hector.api.Cluster;
  import me.prettyprint.hector.api.Keyspace;
  import me.prettyprint.hector.api.factory.HFactory;
  import me.prettyprint.hector.api.mutation.Mutator;
  
  import java.util.UUID;
  
  public class HectorAPI {
      private static final String USER="data";
      public static void main(String[] args) throws Exception{
          StringSerializer ss = StringSerializer.get();
          Cluster cluster = HFactory.getOrCreateCluster("Test Cluster", "127.0.0.1:9160");
          Keyspace keyspace = HFactory.createKeyspace("myKeySpace", cluster);
          String id = UUID.randomUUID().toString();
  
          Mutator&lt;String&gt; mutator = HFactory.createMutator(keyspace, ss);
          mutator.addInsertion(id, USER, HFactory.createStringColumn("full_name", "John"))
                  .addInsertion(id, USER, HFactory.createStringColumn("email", "test"))
                  .addInsertion(id, USER, HFactory.createStringColumn("state","yfcy"))
                  .addInsertion(id, USER, HFactory.createStringColumn("gender", "male"))
                  .addInsertion(id, USER, HFactory.createStringColumn("birth_year", "1990"));
          mutator.execute();
  
      }
  
  }
  </code></pre>

  <p>But there cannot be found any inserted data in /var/lib/cassandra/data folder under the given KeySpace. It seems like data insertion does not work properly. What can be the issue with the code. The command that I have used to create 'data' column family is displayed below.
  <i></p>
  
  <pre><code>CREATE COLUMN FAMILY data
  WITH comparator = UTF8Type
  AND key_validation_class=UTF8Type
  AND column_metadata = [
  {column_name: full_name, validation_class: UTF8Type}
  {column_name: email, validation_class: UTF8Type}
  {column_name: state, validation_class:  UTF8Type, index_type: KEYS}
  {column_name: gender, validation_class: UTF8Type}
  {column_name: birth_year, validation_class: UTF8Type, index_type: KEYS}
  ];
  </code></pre>
