CDPD-33770: On the topics details page selecting a custom timestamp is broken

When you select a custom TimePeriod (a non-predefined TimePeriod like 6 hours, 30 minutes etc.) on the SMM UI's topicDetail page, an error is going to be thrown, and the replication related metrics would not be displayed.

OPSAPS-63017: The Kafka Connect tab is missing from the SMM UI

Under certain circumstances the Kafka Connect tab in SMM might not be available by default on Data Hub clusters even if Kafka Connect is provisioned on the cluster. As a result, interacting with Kafka Connect using SMM is not possible.

1. Access the Cloudera Manager instance managing the affected Data Hub cluster.
2. Select the Streams Messaging Manager service, and go to Configuration.
3. Find and configure the following properties:
   • Kafka Connect Host

     Enter the hostname of the machine that the Kafka Connect role is deployed on. If you have multiple instances of the Kafka Connect role, you can choose to use any of them. Add a single hostname, as configuring multiple hostnames for high availability is currently not supported.

   • Kafka Connect Port

     Enter the port that the Kafka Connect role is using. The value of this property must match the port set in the Secure Kafka Connect Rest Port Kafka property.

   • Kafka Connect Protocol

     Set this property to https.

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>
