Is there currently a way to use Ranger with NiFi to authorize group access?

[#1]

I am able to grant access to users individually using Ranger, however I am unable to use groups in Ranger. Is there some extra configuration needed to allow this? I am using NiFi 1.2.0.

Group policies for NiFi when using Ranger are not supported in the current release, but it will be available in a future HDF release.

If you are using apache, then it is available in Apache NiFi 1.4.0.
