我正在尝试使用 Java 程序连接到 Cassandra 集群，但出现以下错误 -

Caused by: java.lang.IllegalStateException: Detected Guava issue #1635 which indicates that a version of Guava less than 16.01 is in use.  This introduces codec resolution issues and potentially other incompatibility issues in the driver.  Please upgrade to Guava 16.01 or later.

我尝试使用独立 java 并且它工作正常，但在我的项目中抛出错误。它在以下行抛出异常：

this.cluster = Cluster.builder().addContactPoint(node).withPort(port).build();

感谢您的指导。

Answer 1

类路径中的 Guava 版本必须早于 16.0.1。 java驱动只支持Guava 16.0.1到19（即将发布的3.2.0将支持16.0.1到21）。

检查你的类路径是否有旧版本的番石榴并将其替换为 16.0.1 和 19.0 之间的版本。您的应用程序也可能在您的类路径中有多个番石榴罐，在这种情况下，您应该删除旧的。
