Question

我创建了一个maven项目，用于连接cassandra数据库并通过cassandra astyanax java客户端插入数据。

maven clean并成功安装构建但是当我运行这个java应用程序时，我得到以下错误

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/cassandra/dht/Murmur3Partitioner
    at com.netflix.astyanax.impl.AstyanaxConfigurationImpl.<init>(AstyanaxConfigurationImpl.java:55)

Answer 1

Murmur3Partitioner在Cassandra 1.2中被引入。你需要更新你的pom以获得1.2版本而不是1.1版本。

Astyanax“java.lang.NoClassDefFoundError：org / apache / cassandra / dht / Murmur3Partitioner”异常
