Hi Asitha,
Not sure whether you can use this approach or not, previously in ES product
we had following Cassandra data-source[1] definition and able to create
connection using following, But we have used cassandra.cql.jdbc driver here.
CarbonDataSource carbonDataSource =
DataSourceManager.getInstance().getDataSourceRepository().getDataSource("SOCIAL_CASSANDRA_DB");
DataSource dataSource = (DataSource) carbonDataSource.getDSObject();
conn = dataSource.getConnection();
[1]
<datasource>
<name>SOCIAL_CASSANDRA_DB</name>
<description>The cassandra datasource used for storing social
activities</description>
<definition type="RDBMS">
<configuration>
<url>jdbc:cassandra://localhost:9160/EVENT_KS</url>
<username>admin</username>
<password>admin</password>
<driverClassName>org.apache.cassandra.cql.jdbc.CassandraDriver</driverClassName>
</configuration>
</definition>
</datasource>
Regards,
UdaraR
