@felix Albani
Thanks for the viedo.
Sorry to reply after such a long time period.
I have watched and check, but still dont know what I miss config.
Before reinstall HDF and config again, there are some questions I would like to ask.
In the nifi-app.log：
2018-09-05 17:54:07,793 WARN [Thread-22] o.a.r.admin.client.RangerAdminRESTClient Error getting policies. secureMode=false, user=nifi (auth:SIMPLE), response={"httpStatusCode":400,"statusCode":0}, serviceName=hdf_nifi
Do I need to resolve the WARN message in nifi-app.log.
[Error getting policies. secureMode=false, user=nifi (auth:SIMPLE) user=nifi]
Both NiFi and Ranger had been enabled in SSL mode.
But getting policies does not seems run in secure mode.
I have three NiFi ranger plugin certificate with DN [CN=ambari01.test.com, OU=NiFi、CN=ambari02.test.com, OU=NiFi、CN=ambari03.test.com, OU=NiFi]
A nifi user is manually created in Ranger admin UI as internal.
The following images are my Ranger/Ambari screen shot and question
1.Do the nifi user need to create certificate too?
2.Is the nifi user a OS user in NiFi host or also a NiFi application user?
#nifi user in Ranger admin
#ranger_nifi_policymgr
Thanks for your help.
