> The NPE is because _ranger-hdfs-policymgr-ssl_ is a new config type in HDP 2.3 and so the desiredconfig returned in _ConfigureAction_ is null as this config-type does not exist.

> Map<String, DesiredConfig> desiredConfigs = cluster.getDesiredConfigs();
> DesiredConfig desiredConfig = desiredConfigs.get(configType);
> Config config = cluster.getConfig(configType, desiredConfig.getTag());

> Following difference in _UpgradeResourceProvider.java_ between RU and EU seems to be the root cause
> {code}
> /**
> During a Rolling Upgrade, change the desired Stack Id if jumping across
> major stack versions (e.g., HDP 2.2 -> 2.3), and then set config changes
> so they are applied on the newer stack.
> During a {@link UpgradeType.NON_ROLLING} upgrade, the stack is applied during the middle of the upgrade (after
> stopping all services), and the configs are applied immediately before starting the services.
> The Upgrade Pack is responsible for calling {@link org.apache.ambari.server.serveraction.upgrades.UpdateDesiredStackAction}
> at the appropriate moment during the orchestration.
