Description

Currently, kylin servers in a cluster are predefined and can be updated by manually setting the "kylin.server.cluster-servers". It's not flexible if the servers change especially when the servers are able to change automatically in cloud, like k8s.

It's better for servers to self register themselves in zookeeper. With the help of zookeeper, kylin servers can watch the event change and know the whole server layout, which will benefit the Broadcaster and future interesting things, like DAG.
