- CDPD-47616: Unable to initiate rebalance, number of valid windows (NumValidWindows) is zero
- If a Cruise Control rebalance is initiated with the
rebalance_diskparameter and Cruise Control is configured to fetch metrics from Cloudera Manager, Cruise Control stops collecting metrics from the partitions that are moved. This is because Cloudera Manager does not collect metrics from moved partitions due to an issue in Kafka (KAFKA-10320).If the metrics are not available, the partition is considered invalid by Cruise Control. This results in Cruise Control blocking rebalance operations and proposal generation.
