---------------------------------------
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.
