Research direction

Start by reproducing the failure with the official Helm deployment on Kubernetes and trace the stack from KyuubiServer.scala:48 to EmbeddedZookeeper.scala:48. Inspect the chart configuration and the embedded ZooKeeper initialization to determine why embedded_zookeeper/version-2 cannot be created; done means Kyuubi launches successfully with the official chart and the failure is covered by an appropriate test or deployment check.
