Jeff Storck commented on NIFI-3534:
-----------------------------------
Work being done on NIFI-3472 will also allow impersonation. I will try to
incorporate the changes from the pull request for this JIRA into my work on the
controller services that I'm adding.
> Add support for impersonating a user with HDFS processors

> Key: NIFI-3534
> URL: https://issues.apache.org/jira/browse/NIFI-3534
> 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.
