I have been trying to deploy Kafka with schema registry locally using Kubernetes. However, the logs of the schema registry pod show this error message:
ERROR Server died unexpectedly: (io.confluent.kafka.schemaregistry.rest.SchemaRegistryMain:51)
org.apache.kafka.common.errors.TimeoutException: Timeout expired while fetching topic metadata
What could be the reason of this behavior? ' In order to run Kubernetes locally, I user Minikube version v0.32.0 with Kubernetes version v1.13.0
