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)
