[jira] [Created] (HELIX-384) Ideal state replica count behavior is confusing

Kanak Biscuitwala created HELIX-384:
---------------------------------------

             Summary: Ideal state replica count behavior is confusing
                 Key: HELIX-384
                 URL: https://issues.apache.org/jira/browse/HELIX-384
             Project: Apache Helix
          Issue Type: Bug
            Reporter: Kanak Biscuitwala


Right now, the replica count in an ideal state is used in the following ways:

1. If the state model has a state with upper bound R
2. In HelixAdmin#rebalance to compute the preference lists/maps

But it's ignored in every other case, and this is particularly confusing when the state upper bound N is used. The question is: should this replica count trump every other upper bound constraint, even when the state model doesn't have an R bound?
