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
