- You should check whether the CC endpoints are working as expected or not.
- Automatic rebalancing is DISABLED by default but it can be enabled by adding self.healing.enabled=true in cruisecontrol.properties advance snippet on CM UI. You can enable self-healing for specific types of events like broker failures, disk failures, metric anomalies or goal violations, etc.
Self healing is enabled already. When any broker goes down, CC is rebalancing partitions to healthy nodes but when that node comes back up, redistribution is not happening automatically. I have to run the rebalance API manually.
I am expecting to rebalance leaders and replicas. In the example below when broker id 1111 went down, CC self healed(distributed leaders/partitions automatically) to other nodes. When 1111 node came back, distribution not happening automatically.
It looks like you have the case open for the same issue from the Cloudera ticket system and we are replicating and investigating this issue on priority. We will share a workaround in the case and here in this community article as well so that it can help other users if they will come across the same issue.
