Description
Create 3 node cluster
- Failover one node
- Upgrade the node to 7.6.2-3721
- Rebalance(remove out the node) and stop rebalance without it completing
- Add node back, rebalance
The partition count increases for no reason. 18 parition becomes 20 and 3 partitions become 5. This happens for both active and replica parition
