> Many thins can be improved:
> * znodeParentPath could be a local variable
> * zkManager could be private, VisibleForTesting annotation is not needed
> anymore
> * Do something with unchecked casts
> * zkManager.safeSetData calls are almost having the same set of parameters:
> Simplify this
> * Extract zkManager calls to their own methods: They are repeated
> * Remove TODOs
