             Summary: FULL_AUTO rebalancer should not prefer nodes that are just coming up
                 Key: HELIX-277
                 URL: https://issues.apache.org/jira/browse/HELIX-277
             Project: Apache Helix
          Issue Type: Sub-task
            Reporter: Kanak Biscuitwala
            Assignee: Kanak Biscuitwala


Rebalancing in FULL_AUTO mode will relentlessly (though mostly greedily) seek a balance in both partitions and states across nodes with minimal movement. However, in this pursuit, we may end up requiring multiple transitions to get a node in the right state for a given partition.

We can fix this by refusing to prefer nodes as they come up, and then revert to the existing strategy once their current state contains a replica.
