Subject Keytab Configuration for Nifi processor
Date Thu, 08 Jun 2017 20:00:40 GMT
Hi

I have Nifi 3 node cluster (Installed Via Hortonworks Data Flow - HDF ) in
Kerborized environment. As part of installation Ambari has created nifi
service keytab .

Can I use this nifi.service.keytab for configuring processors like PutHDFS
who talks to Hadoop services ?

The nifi.service.keytab is machine specific and always expect principal
names with machine information. ex nifi/HOSTNAME@REALM

If I configure my Processor with nfii/NODE1_Hostname@REALM information then
I see kerberos authentication exception in other two nodes.

How do I dynamically resolve hostname to use nifi service  keytab  ?

Thanks
Shashi
