Kubernetes elasticsearch连接器没有'；t work-java.lang.NoClassDefFoundError:com/google/common/collect/ImmutableSet

Kafka elasticsearch连接器“confluentinc-Kafka-connect-elasticsearch-5.5.0”在prem上不工作

我已经阅读了一些消息，elasticsearch连接器中缺少jar文件/依赖项，我添加了它们，正如您在上面看到的，但没有运气

这是我的连接器配置：

我将用户名/密码更改为明文；不走运。 我尝试了两种http/https的elasticsearch连接，没有运气

这是我的elasticsearch srv信息：

无论我做什么，例外永远不会改变。我不知道还有什么我可以试试的。我的大脑在燃烧，我快要发疯了

我遗漏了什么，或者你们能告诉我你们是如何在库伯内特斯的prem上运行这个连接器的吗

感谢和问候

我正在使用《卡夫卡2》。12-2.5.0我也遇到了同样的问题。我注意到$KAFKA_HOME/libs中缺少与KAFKA

2相关的番石榴罐子。4.0

。作为一种解决方法，我从以前的卡夫卡发行版中手动复制了jar（

guava-20.0.jar

），一切正常。

您如何在Kafka Connect worker中安装连接器？我使用“Strimzi Kafka Operator”部署连接器。我首先让它独立工作，然后尝试让它与Strimzi一起工作。您如何在Kafka Connect worker中安装连接器？我使用“Strimzi Kafka Operator”部署连接器。我首先让它独立工作，然后尝试让它与Strimzi一起工作。将缺少的

添加到工作节点容器的
