Known issues in Cruise Control
Learn about the known issues in Cruise Control, the impact or changes to the functionality, and the workaround.
- OPSAPS-60810: Cruise Control script overrides security related properties added to Safety Valve
- The security related properties (security.protocol) for Cruise Control are added at the end of the properties file which are later appended to the Cruise Control configuration file. Due to a bug in the control script, the security properties that are added to the Safety Valve are overridden and not propagated to the configuration file of Cruise Control. This can cause failure when starting Cruise Control.
- 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.
