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

Github user StephanEwen commented on the issue:

    https://github.com/apache/flink/pull/4382
  
    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)
    
      -
