----------------------------------------
Summary: IllegalArgumentException in RangerRESTClient when no
ranger.plugin.<service>.policy.rest.url is configured
Key: RANGER-5397
URL: https://issues.apache.org/jira/browse/RANGER-5397
Project: Ranger
Issue Type: Bug
Components: Ranger
Affects Versions: 2.7.0, 2.6.0, 2.5.0
Reporter: Vyom Mani Tiwari
Assignee: Vyom Mani Tiwari
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));}}}
