jtstorck commented on issue #3279: NIFI-5984: Enabled Kerberos Authentication for PutKudu URL: https://github.com/apache/nifi/pull/3279#issuecomment-460355086 > The code LGTM, I'm not able to give it a try right now unfortunately. Just one question though: does it take care of the ticket renewal? or is the underlying implementation taking care of it? (asking since the client is initialized in the OnScheduled method) UGI will take care of the relogin, but I think only if the UGI.doAs is used to execute the action. If the PR is updated to use KerberosAction from nifi-security-utils org.apache.nifi.security.krb.KerberosAction, it will handle expired tickets.
