```

## Additional information you deem important:

* changes you did or observed in the environment

It seems that invoker crash because `config.ZookeeperHosts` is null string.
This may be caused by #5375 which remove it from invoker, however, CuratorFrameworkFactory.newClient requires it to be not null when zookeeper is used.

Adding ZookeeperHosts to the requiredProperties solves this bug.
