Ignite + cassandra Cannot find class [com.datastax.driver.core.policies.TokenAwarePolicy] for bean with name 'loadBalancingPolicy'

Question

i m trying to integrate Apache Ignite with Apache Cassandra(Cassandra 3.11.10) as I want to use Ignite to cache the data present in Cassandra. I Created 3 xml files :

1. content of cassandra-config.xml

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!-- Persistence settings for 'cache1' -->

        <constructor-arg type="org.springframework.core.io.Resource" value="file:/opt/ignite/config/persistance-settings.xml" />
    </bean>
    <!-- Ignite configuration -->

                            -->
                            <property name="persistenceSettingsBean" value="cache1_persistence_settings"/>
                            <!--

                            index secondaires, sérialiseur pour les objets BLOB et etc…​)

                </bean>
        </property>
    </bean>
</beans>

2. content of connection-settings.xml:

3. content of persistance-settings.xml :

<persistence keyspace="K_ignite" table="T_ignite">
    <keyspaceOptions>
        REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor' : 1}
        AND DURABLE_WRITES = true
    </keyspaceOptions>
    <keyPersistence class="java.lang.String" strategy="PRIMITIVE"/>
    <valuePersistence class="org.mycompany.MyValueClass" strategy="BLOB"/>
</persistence>

I run the following command to start Ignite

$ ignite.sh cassandra-config.xml

i get this error :

Note! You may use 'USER_LIBS' environment variable to specify your classpath.

NB I'm using the same node for both Cassandra and Ignite (localhost)

please, any suggestions or tips to follow to solve this problem

thanks in advance
