Cloudera Runtime Release Notes

Fixed Issues in Apache Kafka

Review the list of Apache Kafka issues that are resolved in Cloudera Runtime 7.2.14.

CDPD-27780: IdentityReplicationPolicy for MM2 to mimic MM1 (KAFKA-9726 backport): warning
The IdentityReplicationPolicy does not detect cycles. As a result, using this replication policy is only viable in deployments where the replication setup is acyclic. If your replication setup is not acyclic, using this replication policy might result in records being replicated in an infinite loop between clusters. Additionally, monitoring replications with the SRM Service is not possible when this policy is in use.
This is a backported improvement that introduces a new replication policy called IdentityReplicationPolicy. This replication policy does not rename remote (replicated) topics. As a result of this backport, the IdentityReplicationPolicy is now available for use with Streams Replication Manager. For more information, see KAFKA-9726.
OPSAPS-61697: Kafka broker IDs are overridden when importing a cluster template: Importing a cluster template to a new cluster in Cloudera Manager no longer overrides Kafka broker IDs (broker.id) or other role specific unique identifiers if the unique identifiers are already set in the template.
