本文提供了一个使用Hector Java客户端库操作Cassandra的示例代码，演示了如何配置集群连接、创建Keyspace、定义列族并插入数据。

import me.prettyprint.cassandra.serializers.StringSerializer;
import me.prettyprint.cassandra.service.CassandraHostConfigurator;
import me.prettyprint.hector.api.Cluster;
import me.prettyprint.hector.api.Keyspace;
import me.prettyprint.hector.api.factory.HFactory;
import me.prettyprint.hector.api.mutation.Mutator;

public class ExampleClient {

public static void main(String[] args) throws IllegalStateException,Exception {
CassandraHostConfigurator cassandraHostConfigurator=new CassandraHostConfigurator("192.168.100.108:9160,192.168.100.110:9160");
cassandraHostConfigurator.setMaxActive(20);
cassandraHostConfigurator.setMaxIdle(5);
cassandraHostConfigurator.setCassandraThriftSocketTimeout(3000);
cassandraHostConfigurator.setMaxWaitTimeWhenExhausted(4000);

StringSerializer stringSerializer=new StringSerializer();
Cluster cluster=HFactory.createCluster("cluster_name", cassandraHostConfigurator);

Keyspace ks=HFactory.createKeyspace("OBS", cluster);
String columnFamily = "bucket";
Mutator mutator =HFactory.createMutator(ks, stringSerializer);

mutator.insert("bucket_key", columnFamily, HFactory.createStringColumn("object_name", "object_value"));
System.out.println("testHetor");
cluster.getConnectionManager().shutdown();
}
}
