OPSAPS-59597: Streams Messaging Manager UI logs are not supported by Cloudera Manager
Cloudera Manager does not display a Log Files menu for Streams Messaging Manager UI role (and Streams Messaging Manager UI logs cannot be displayed in the Cloudera Manager UI) because the logging type used by Streams Messaging Manager UI is not supported by Cloudera Manager.
View the Streams Messaging Manager UI logs on the host.
CDPD-39313: Some numbers are not rendered properly in Streams Messaging Manager UI
Very large numbers can be imprecisely represented on the UI. For example, bytes larger than 8 petabytes would lose precision.
None.
OPSAPS-59553: Streams Messaging Manager bootstrap server config should be updated based on Kafka's listeners
Streams Messaging Manager does not show any metrics for Kafka or Kafka Connect when multiple listeners are set in Kafka.
Streams Messaging Manager cannot identify multiple listeners and still points to bootstrap server using the default broker port (9093 for SASL_SSL). You need to override bootstrap server URL (hostname:port as set in the listeners for broker). Add the bootstrap server details in Streams Messaging Manager safety valve in the following path:
  1. In Cloudera Manager, go to SMMConfigurationStreams Messaging Manager Rest Admin Server Advanced Configuration Snippet (Safety Valve) for streams-messaging-manager.yaml.
  2. Add the following value for bootstrap servers.
    streams.messaging.manager.kafka.bootstrap.servers=<comma-separated list of brokers>
  3. Save your changes.
  4. Restart Streams Messaging Manager.
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 Streams Messaging Manager 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.
None.
CDPD-78694: Streams Messaging Manager UI cannot show replication details
The Kafka cluster replication details view is not available on the Cluster Replications page because the UI does not pass the required duration URL parameter when calling the Streams Messaging Manager REST Admin server.
You can query replication details by manually calling the Streams Messaging Manager REST Admin server with the required duration URL parameter.
