Should there be any validation that prevents setting remote user and also
providing a kerberos principal/keytab since it the remote user would be ignored
in that case? or maybe just document in the description of the property that it
is only used when not using kerberos?

>
> When using the HDFS processors, specifically PutHDFS there are times when a
> user wants to impersonate a user so that the files written to HDFS are done
> as the remote user. In cases where Kerberos is not used, this is not
> possible. Currently there is the ability for NiFi to change the permissions
> using the Remote Owner and Remote Group, however, this only works if NiFi is
> running as a user that has HDFS super user privilege. By providing the
> ability to set a Remote User, NiFi can then impersonate the user and the
> permission checks will be done in Hadoop land.
