CDPD-39313: Some numbers are not rendered properly in SMM UI
Very large numbers can be imprecisely represented on the UI. For example, bytes larger than 8 petabytes would lose precision.
CDPD-45183: Kafka Connect active topics might be visible to unauthorised users
The Kafka Connect active topics endpoint (/connectors/[***CONNECTOR NAME***]/topics) and the Connect Cluster page on the SMM UI disregard the user permissions configured for the Kafka service in Ranger. As a result, all active topics of connectors might become visible to users who do not have permissions to view them. Note that user permission configured for Kafka Connect in Ranger are not affected by this issue and are correctly applied.
CDPD-46465: Searching for workers on the connector overview page freezes the page
Navigating to the SMM UI Connectors page selecting the Cluster Profile tab and filtering for hosts using the search field causes the page to freeze.
CDPD-46728: SMM UI shows the consumerGroup instead of the instances on the Profile page's right hand side
On the ConsumerGroupDetail page, SMM UI shows the group instead of its instances on the right hand side table.
OPSAPS-59553: SMM's bootstrap server config should be updated based on Kafka's listeners
SMM does not show any metrics for Kafka or Kafka Connect when multiple listeners are set in Kafka.
SMM cannot identify multiple listeners and still points to bootstrap server using the default broker port (9093 for SASL_SSL). You would have to override bootstrap server URL (hostname:port as set in the listeners for broker). Add the bootstrap server details in SMM safety valve in the following path:
Cloudera Manager > SMM > Configuration > Streams Messaging Manager Rest Admin Server Advanced Configuration Snippet (Safety Valve) for streams-messaging-manager.yaml > Add the following value for bootstrap servers > Save Changes > Restart SMM.
streams.messaging.manager.kafka.bootstrap.servers=<comma-separated list of brokers>
OPSAPS-59597: SMM UI logs are not supported by Cloudera Manager
Cloudera Manager does not support the log type used by SMM UI.
