if your hadoop cluster is kerberosed, try to add ha.zookeeper.acl.enabled false

[yaooqinn]

kyuubi.ha.zookeeper.quorum host:port
kyuubi.zookeeper.embedded.client.port is for embedded zk server，it is not for multi–server ha but only a single node

[pan3793]

kyuubi.ha.enabled=true
kyuubi.ha.zookeeper.quorum=host1:2182,host2:2182,host3:2182

[merrily01]

Is it possible that there is a problem with the permissions of the zk directory? You can check after logging in through the zk client. Or try changing the default namespace path through 'kyuubi.ha.zookeeper.namespace'.
