    [FLINK-7241] Rename namespace to cluster-id in HA doc
    
    This was renamed a while ago and namespace is now deprecated.

commit 6b15600baa706cf89a585bd0a1bb5cd3e0df8969

    [FLINK-7241] Remove cluster-id from YARN HA setup template in doc
    
    When running a YARN cluster the cluster-id is automatically derived.
    Acutally setting a cluster-id can lead to problems if you start multiple
    per-job YARN sessions with the same cluster-id by accident.

[GitHub] flink issue #4382: [FLINK-7241] Fix YARN high availability documentation

    I would go a bit further in updating this:
    
      - The ZooKeeper root node has a default value of `/flink` (I think). You only need to set this when you want to organize your ZooKeeper node tree in a specific way.
    
      - The cluster-id docs should be changed to say that you *do not need to set this manually* in Yarn / Mesos mode and that it generates a new subtree per launch. You only need to set this if you want to manually recover an earlier HA job (which is different from re-launching the job from a savepoint or externalized checkpoint)
    
      -
