Review the list of Cruise Control issues that are resolved in Cloudera Runtime 7.1.5.

OPSAPS-58297: Cruise Control might fail after CDP Private Cloud Base upgrade

The default Cruise Control configuration for Process Start Retry Attempts has been changed to avoid failing after CDP Private Cloud Base upgrade. The metric collector will restart more times to ensure that Cruise Control has all the needed metrics to start.

CDPD-19200: Cruise Control cannot collect metrics if Kafka topics have dot in their name

The Cloudera Manager metrics fetcher returns topic and topic-partition metrics with dot in their topic name field. This caused failure in the metrics collection as Cruise Control expected the Kafka default form using underscores. Cruise Control has been changed to also collect the metrics from the topics and topic-partitions that have dots in their name field.
