Description

Livy can store its state in ZooKeeper for recovery ("livy.server.recovery.state-store": "zookeeper"). In this case livy.server.recovery.state-store.url should point to the ZooKeeper quorum.

Setting "livy.server.recovery.state-store.url": "%HOSTGROUP::quorum%:2181" should be enough to specify ZK servers in a host group named quorum. However, since it is not explicitly handled in BlueprintConfigurationProcessor, the placeholder is replaced only with a single address.
