error_description
].
The internal process that is responsible for Kafka communication tested a connection to Kafka but the test failed because of a Class Not Found exception. This error is not fatal. This informational message is issued only when the process tests connectivity to or availability of the Kafka instance and the test fails.
Typically, this message indicates that not all of the Kafka client library files have been added to the generated classpath. Review the product documentation to determine how to properly add the Kafka client libraries to the environment. Then ensure that all of the Kafka libraries have been included.
