Description

Ranger Admin REST Client fails on calling getServicePoliciesIfUpdated method if running inside hiveserver2 Interactive.

The stack trace is the following:

The error seems generated by the buildClient() method that always returns null. Running the plugin inside hiveserver2 (non interactive) works well.

 

Current workaround to use updated policies from ranger admin is to install both hiveserver2 and hiveserver2 Interactive on the same host
