I have HDP 3.1 Kerberized cluster where Ranger is also installed. Nifi ranger plugin is enabled . When I am trying to view NIFI default policy on Ranger its not visible.
I get an error in Ranger logs saying :-
2019-05-10 05:57:27,688 [http-bio-6080-exec-15] WARN org.apache.ranger.biz.ServiceDBStore (ServiceDBStore.java:2589) - Default policy won't be created,since policyItems not valid-either users/groups not present or access not present in policy.
I check the NIFI configuration for Ranger but nothing seems to be working. Some help would be appreciated.
