[jira] [Created] (HELIX-357) Choose full auto node capacity based on existing assignment

Kanak Biscuitwala created HELIX-357:
---------------------------------------

             Summary: Choose full auto node capacity based on existing assignment
                 Key: HELIX-357
                 URL: https://issues.apache.org/jira/browse/HELIX-357
             Project: Apache Helix
          Issue Type: Improvement
            Reporter: Kanak Biscuitwala
            Assignee: Kanak Biscuitwala


If R mod N = K, then the auto rebalance strategy just picks the first K nodes in lexicographic order and gives them an extra unit of capacity. The algorithm instead should award that unit of capacity to nodes that already have the most assigned partitions.
