             Summary: Refactor YarnClusterDescriptor inheritance
                 Key: FLINK-14050
                 URL: https://issues.apache.org/jira/browse/FLINK-14050
             Project: Flink
          Issue Type: Sub-task
          Components: Client / Job Submission, Command Line Client
    Affects Versions: 1.10.0
            Reporter: TisonKun
             Fix For: 1.10.0


Currently, the inheritance looks like

{{AbstractYarnClusterDescriptor}}
    -> {{YarnClusterDescriptor}}
    -> {{TestingYarnClusterDescriptor}}
    -> {{NonDeployingYarnClusterDescriptor}}
    ->    -> {{NonDeployingDetachedYarnClusterDescriptor}}

With an investigation, I find

1. {{AbstractYarnClusterDescriptor}} is introduced for migration purpose and no need any more.
2. {{TestingYarnClusterDescriptor}} is redundant and can be replaced directly with {{YarnClusterDescriptor}}.
3. Some methods like {{#createYarnClusterClient}} have parameters that never used, which are for historical reasons.

Thus, I propose we refactor {{YarnClusterDescriptor}} inheritance 
{{YarnClusterDescriptor}}
    -> {{NonDeployingYarnClusterDescriptor}}
    ->    -> {{NonDeployingDetachedYarnClusterDescriptor}}

and also methods remove unused parameters.
