> {{AbstractYarnClusterDescriptor}} should be made immutable. Currently, its 
> internal configuration is modified from different places which makes it 
> difficult to reason about the code. For example, it should not be possible to 
> modify the {{zookeeperNamespace}} using a setter method. A user of this class 
> should be forced to provide all information prior to creating the instance, 
> e.g., by passing a {{org.apache.flink.configuration.Configuration}} object.
