Hi Prabath,
Found the root cause with the help of SameeraJ. Below exceptions occurred
when calling initSystemDataSources() method because following dependencies
not available in org.wso2.carbon.cassandra.datareader.feature. It's working
without issue once I add these dependencies to
org.wso2.carbon.cassandra.datareader.feature and build product-mb. Shall I
send you a pull request with changes I made to
org.wso2.carbon.cassandra.datareader.feature?
