Hi Venkat,
The current approach to connect HANA to SUP is still considered a "hack". Like I said earlier, you basically need to copy the jdbc client to your SUP server and Mobile SDK, and then configure the connection. Please start with the documentation I attached in above post first, and see how far you can get from there. You can download the latest jdbc driver from developers.sap.com/hana.
I hope this helps.
