根据日志内容，看起来是Kafka的错误，而不是Canal的问题。可能是Kafka集群中的某个broker不可用，导致LEADER_NOT_AVAILABLE错误。建议您检查Kafka集群的状态，确保所有broker都在运行中，并且Kafka主题是否已正确创建。您可以运行以下命令来检查Kafka集群状态：
bin/kafka-topics.sh --describe --zookeeper <zookeeper_host>:<zookeeper_port> --topic <topic_name>如果Kafka集群和主题都已正确配置，则建议您检查Canal的配置文件中的Kafka配置是否正确。
