Thank you for contributing this! I did a quick first pass from a Kudu perspective. Someone with more NiFi knowledge should review too.

Should this version be pulled up to a property in the bundle pom so it can be unified/shared with the processors? All the usages below too.

@pvillard31 given you reviewed the PutKudu changes from a NiFi perspective, would you be interested in reviewing this one too?

the travis build does not work

So this need to be fixed. Otherwise this looks ready to go to me excluding perhaps that I'm surprised there are no L&N considerations for the lookup nar. But I've not confirmed if this is just part of the kudu nar yet.

[SamHjelmfelt]

The Travis build for Java 8 EN succeeded, but the others failed due to a check-style issue in nifi-shell-authorizer (src/test/java/org/apache/nifi/authorization/ShellUserGroupProviderIT.java). This check-style issue was fixed in NIFI-6400.
