Yes. The component which will be interfacing with hadoop will be deployed in an application server. And the application server runs on 1.5 only. Therefore, we cannot migrate to 1.6.
At present I am thinking of decoupling the component from hadoop so that this component can run from within the application server and develop another component which would interface with this component. While the old component can run on 1.5, the second component will be executed as a separate process using 1.6 and interface with hadoop. In this way, we would be able to easily upgrade to future hadoop versions without causing any impact on the application server.
