How Can I Address the Issue That Running the Producer.java Sample to Obtain Metadata Fails and "ERROR fetching topic metadata for topics..." Is Displayed?
Troubleshooting Procedure
- Find bootstrap.servers in client.properties under the conf directory of the project, and check whether the IP address and port ID are configured correctly.
- If the IP address is inconsistent with the service IP address of the Kafka cluster, change the IP address to the correct one.
- If the port ID is 21007 (port with Kerberos authentication enabled), change it to 9092 (port with Kerberos authentication disabled).
- Check whether network connections are correct to ensure that the current device can access the Kafka cluster normally.
