Description

Prerequisite: flag IGNITE_DISABLE_WAL_DURING_REBALANCING is set to true (default value is false).

Scenario:

• Node joins the grid and starts rebalancing all cache groups from scratch (e.g. all db files of the node were cleaned up during its downtime);
• One or more client nodes join topology when rebalancing is in progress.

Expected outcome:
Rebalance finishes, node owns all received partitions, new affinity is applied.

Actual outcome:
Rebalance finishes, but node doesn't own any of received partitions, no affinity changes take place.
