>
> RangerBasePlugin initialization fails with an IllegalArgumentException when
> the {{ranger.plugin.<serviceType>.policy.rest.url}} property is not set.
>
> The issue occurs because {{getConfiguredURLs()}} returns an empty list,
> causing {{Random.nextInt(0)}} to throw an exception.
>
> Proposed fix: Handle the case where {{getConfiguredURLs()}} returns an empty
> list, logging a warning and setting a default value.
>
> {{int size = getConfiguredURLs().size();if (size == 0) {LOG.warn("No policy
> REST URL configured for service '{}'",
> serviceType);setLastKnownActiveUrlIndex(0);} else
> {setLastKnownActiveUrlIndex(new Random().nextInt(size));}}}
