Harsha, There are two NARs associated with Hive components, nifi-hive-services-api-nar which has the Hive1_1ConnectionPool service (actually an interface, but that's under the hood), and the nifi-hive1_1-nar which has the processors that declare themselves as users of that interface (and the actual implementations). Did you keep the old Hive 1.1 NAR in the lib/ folder when you upgraded? I would think if you removed the 1.9.2 NARs and used just the 1.11.4 NARs, NiFi would only find the newer ones and automatically upgrade the existing processors and controller services, but I haven't tried it myself. I suspect if they are both present then NiFi will try to match the version of the processors to the controller services and they won't match. Either you'd need both 1.9.2 NARs (the services-api one and the processors one) or neither, I recommend the latter so the components get upgraded to the latest version and that they match. If you're doing a hot reload by dropping the NARs into the dynamic loading location, you'll probably want to remove the old ones entirely, put the new ones in lib/, and restart NiFi.
