> Add support for node groups to FileAccessPolicyProvider
> -------------------------------------------------------

> Key: NIFI-5542
> URL: https://issues.apache.org/jira/browse/NIFI-5542
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Andrew Christianson
> Priority: Major
>
> Currently in FileAccessPolicyProvider, it is possible to specify a set of
> node identities, which are given access to /proxy. This works well for static
> clusters, but does not work so well for dynamic clusters (scaling up/down #
> of nodes) because we don't know in advance what the node identities will be
> or how many there will be.
> In order to support dynamic sets of node identities, add support for
> specifying a "Node Group," for which all identities in the group will be
> granted access to /proxy. A UserGroupProvider can then be implemented to
> gather node identities dynamically from the cluster environment.
