Further debugging, I found the issue is related to JAAS authentication at the application level. On failover the user principal is reset to null on second node hence, I can;t access the secured resources. My expectation is as I logged into application on node1 (user principal is set correctly)... the same principal should be replicated on node2. Any pointers would be highly appreciated.
