--------------------------------------
Fix Version/s: 2.8
> Rebalancing overwhelmingly prefers some supplier nodes to others
> ----------------------------------------------------------------
>
> Key: IGNITE-11745
> URL: https://issues.apache.org/jira/browse/IGNITE-11745
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.7
> Reporter: Ilya Kasnacheev
> Assignee: Ilya Kasnacheev
> Priority: Critical
> Fix For: 2.8
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When cache has backups, and you add third node to cluster, Ignite will only
> rebalance data from single node.
> When you add n-th node, Ignite will not rebalance from some nodes and it will
> pull 10x as much data from some nodes than from others.
> This is because we filter static nodes list by partition availability and
> then pick the first one. Overwhelmingly it is the first nodes in list and
> nodes towards the end of list will never get to supply partitions.
