java - 赫克托与 Cassandra 联系

Question

我正在尝试将 Cassandra 与 Hector 联系起来:

public class Main {
    public static void main(String[] args) {
        StringSerializer stringSerializer = StringSerializer.get();
        Cluster cluster = HFactory.getOrCreateCluster("Test Cluster", "localhost:9160");
        Keyspace keyspace =  HFactory.createKeyspace("Keyspace1", cluster);
        Mutator<String> mutator = HFactory.createMutator(keyspace, stringSerializer);
        mutator.insert("jsmith", "Standard1", HFactory.createStringColumn("first", "John"));
    }

}

问题:

我该如何解决？

我已经对 hector 和 cassandra 失去了最后的耐心，我尝试连接但失败了。我运行 twissjava 示例并且它有效，但是当我扩展主类以进行我自己的测试时它不运行。

这个问题“记录在 "SLF4J in Hector"-page 的 wiki 上

精简版:您需要添加一个实现 SLF4J api 的库。
