Kafka流: PolicyViolationException:主题复制因子必须为3
Kafka流: PolicyViolationException:主题复制因子必须为3
提问于 2020-02-12 18:14:39
目前，我正在构建一个应用程序，该应用程序写入一个kafka主题，并侦听该主题，从中生成一个ktable并将其具体化到存储中。我正在运行的代码基于下面的示例。我几乎复制了其中的大部分(除了PageViewEventSource)，并将名称重构到我的用例中。我还用示例中使用的键更新了我的application.properties。
在运行应用程序时，我会得到以下错误：
2020-02-12 17:54:31.982 ERROR 69005 --- [-StreamThread-1] o.a.k.s.p.i.InternalTopicManager : stream-thread [restartedMain] Unexpected error during topic creation for pairing-events-pcmv-changelog.
Error message was: org.apache.kafka.common.errors.PolicyViolationException: Topic replication factor must be 3
