> Project: Ranger
> Issue Type: Bug
> Components: plugins
> Affects Versions: 0.5.0, 0.5.1, 0.5.2, 0.6.0
> Reporter: Madhan Neethiraj
> Assignee: Alok Lal
>
> Ranger policy engine initialization does not expect NULL value for a resource
> (like path). When a policy has such a value, the initialization fails with
> NPE. Policy engine should be updated to ignore NULL values.
> java.lang.NullPointerException
