----------------------------------------
Summary: 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
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.
