Description

When reading the code, I found a deprecated method to use. In ZKDelegationTokenSecretManager#startThead, the code here uses the Curator's EnsurePath,
But EnsurePath is deprecated, use the recommended method instead

public class EnsurePath
Deprecated.
Since 2.9.0 - Prefer CuratorFramework.create().creatingParentContainersIfNeeded() or CuratorFramework.exists().creatingParentContainersIfNeeded()
