Configuring Page Size in Ignite's configuration xml 

In the config.xml, the following lines sets the "Page Size".
<bean class="org.apache.ignite.configuration.IgniteConfiguration">
  <property name="dataStorageConfiguration">
    <bean class="org.apache.ignite.configuration.DataStorageConfiguration">

      <!-- Set the page size to 8 KB -->
      <property name="pageSize" value="8192"/>
    </bean>
  </property>

  <!--- Additional settings ---->
</bean>
As per my understanding, the data entered by the client, is stored in 'pages' in the memory, therefore, if I increase the page-size, more number of key-value pairs can be accommodated in the same page. I was thinking that, this size might affect the throughput therefore I wanted to increase the size, however, I'm unable to do so. I get the following error:
ERROR: Failed to instantiate configuration from Spring XML: ./../../../config/config.xml
Ignite seems to be accepting only 8 KB as the value of page Size. Why is this happening?
