Github user bbende commented on the issue: https://github.com/apache/nifi/pull/2582 @jtstorck I tested this against a 2.6 Hadoop with Kerberos and also a 3.0.0 and it appears to work against both so I'm planning to merge this. I do think we should make it as easy as possible for users to get the older NARs if for some reason they really do need to use the 2.x Hadoop client. The easiest way to do this would be to just grab from Nexus and drop them into the lib directory: http://central.maven.org/maven2/org/apache/nifi/nifi-hadoop-libraries-nar/1.6.0/nifi-hadoop-libraries-nar-1.6.0.nar http://central.maven.org/maven2/org/apache/nifi/nifi-hadoop-nar/1.6.0/nifi-hadoop-nar-1.6.0.nar I'm thinking we can either put links to these on our main Downloads page, or we can link to them in the Migration Guidance Wiki page.
