Hello Everyone, We are planning to upgrade our cluster from HDP 2.6.5 to CDP 7.1.1. Can somebody suggest me what are the key areas and points to be considered before upgrade. And any precautions we need take while upgrading, our major workloads are running in Hive, spark also we have Atscale, Nifi.  so it would be really helpful if I get at least some basic things to be focused.   Many Thanks, Ganesan ...
