This topic describes known issues for using Streams Messaging Manager in this release of
Cloudera Runtime.
- 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.
- Workaround: 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-59828: SMM cannot connect to Schema Registry when TLS is enabled
-
When TLS is enabled, SMM by default cannot properly connect to Schema Registry.
As a result, when viewing topics in the SMM Data Explorer with the deserializer key or value
set to Avro, the following error messages are shown:
- Error deserializing key/value for partition [***PARTITION***] at offset [***OFFSET***].
If needed, please seek past the record to continue consumption.
- Failed to fetch value schema versions for topic : '[***TOPIC**]'.
-
In addition, the following certificate error will also be present the SMM log:
- javax.net.ssl.SSLHandshakeException: PKIX path building failed:...
-
Workaround: Additional security properties must be set for SMM.
- In Cloudera Manager, select the SMM service.
- Go to Configuration.
- Find and configure the SMM_JMX_OPTS property.
-
Add the following JVM SSL properties:
- Djavax.net.ssl.trustStore=[***SMM TRUSTSTORE LOCATION***]
- Djavax.net.ssl.trustStorePassword=[***PASSWORD***]
