Question

我有一个使用KafkaSpout的风暴拓扑（不是我写的）。当它启动时，尝试从/kafkaroot/topicname/partition_0读取Kafka主题状态。当我使用kafka-topics.sh创建Kafka主题时，会将其添加到/brokers/topics/topicname/partition/0。我应该改变什么？我有一个错误UnresolvedAddressException，我认为这与此有关。

Answer 1

我认为运行KafkaSpout的服务器无法解析brokerhost主机名。你可以从运行风暴拓扑的服务器ping你的brokerhost吗？或者尝试命令

telnet brokerHosts brokerPort

KafkaSpout从以下位置读取分区信息：... / partition_0 - ＆gt;空值
