Hi Deka,
can you provide some more details about your issue?
I have never heard about mapr-db.
You might want to check if there is a JDBC-Type-4-Driver (hopefully with DataSouce class) for mapr-db.
If such a driver exists you might be able to connect to mapr-db via JDBC Adapter (requires DataSource class) or WmDB package.
Regards,
Holger
