@vperiasamy I added this after my post : nifi.security.identity.mapping.pattern.kerb = ^(.*?)@(.*?)$ nifi.security.identity.mapping.value.kerb = $1 The policy is now working but I get the following error : Untrusted proxy corenifi01-vm.zzzzz.com Do I have to add the nodes of my cluster in Active Directory as well or do I have to add the nodes of my cluster in Ranger (principal is : corenifi01-vm.zzzzz.com@ZZZZZ.COM) ? I added them at the beginning but with this name : corenifi01-vm.zzzzz.com@AA.ZZZZ.COM

Hi, I have a cluster with 2 nodes, installed HDF and use Ranger for security policies. I just installed kerberos on my cluster using an existing AD. I am now trying to connect to NiFi UI but I have insufficient privileges (login/password is ok). I created a policy READ/WRITE for my user raphael.mary (existing in AD) on /* like following : When I try to connect to NiFi I have insufficient privileges and I get this in Ranger Audt : The user trying to connect is raph.mary@ZZZZ.COM 1. Is that normal that the user name is with the realm name in the audit log? 2. When I try to connect I use raphael.mary as login, do I need to specify another user name? Thank you for your help.

Hi, I would like to create an external table in Hive on different databases (MySQL, Oracle, DB2..) because I do not want to move the data, either in HDFS or in Hive directly. How can I do that?

It happened that I imported a template with the processor GetTwitter and the version of the processor seemed to be old. I removed it and added a new one from the tool bar. It works now!

I did but I have no more information in debug mode : 2017-04-28 14:05:35,507 ERROR [Timer-Driven Process Thread-8] o.a.nifi.processors.twitter.GetTwitter GetTwitter[id=60003148-812e-14ce-9c95-0df056d3325d] Received error HTTP_ERROR: HTTP/1.1 401 Authorization Required. Will attempt to reconnect

@apsaltis I already did and I even tested with another application (in java) and it works. Do I need to test the connection to Twitter in command line like a ping or something ? I can ping dev.twitter.com

@Matt Clarke Even with debug level I get this in nifi-app.log : 2017-04-28 14:05:35,507 ERROR [Timer-Driven Process Thread-8] o.a.nifi.processors.twitter.GetTwitter GetTwitter[id=60003148-812e-14ce-9c95-0df056d3325d] Received error HTTP_ERROR: HTTP/1.1 401 Authorization Required.

@Michael Young I added the certificate of twitter (twittercom.crt) in NiFi keystore (with keytool) but get the same error. Do I have to add it in the keystore or the trustore? I did not find any doc on that. The error mentions HTTP_ERROR, but if I am using SSL, why is it not HTTPS?

@Michael Young I tried sample and filter endpoint but I am still getting the same error. Do I need to use certificates because I actived ssl?
