> Now, we use CuratorFramework to simplifies using ZooKeeper in
> ZKDelegationTokenSecretManagerImpl and we always hold the same
> zookeeperClient after initialization ZKDelegationTokenSecretManagerImpl. But
> in some cases like network problem , CuratorFramework may close current
> zookeeperClient and create new one. In this case , we will use a zkclient
> which has been closed to get token. We encountered this situation in our
> cluster，exception information in attachment.
