@apsaltis LGTM but is there chance of making reference to proxyuser groups/
proxyuser hosts in the description or additional info? HDFS Impersonation is
one of those thing people always get wrong the first time they do.

> Add support for impersonating a user with HDFS processors

> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Andrew Psaltis
> Assignee: Andrew Psaltis
>
> 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.
