如何用java实现基于JedisCluster对象的连接池？ 报错

"

今天做了一个基于redis集群的java小demo，用于从hadoop中读取文件，然后写入redis集群，但是单个JedisCluster连接在生产中不够效率，不知道哪位大神能给点基于JedisCluster的连接池示例？ 下面是我的一点代码 `static { URL.setURLStreamHandlerFactory(new FsUrlStreamHandlerFactory()); }

public static void main(String[] args) throws Exception { writeRedis("hdfs://mycluster/test/test.txt",new int[]{0}); //writeRedis(initConfig()); }

public static void writeRedis(String inpath, int[] keyIndex) throws Exception {
    InputStream in = new URL(inpath).openStream();// 输入流 ]
    LineIterator br = org.apache.commons.io.IOUtils.lineIterator(in, "utf8");// 指定输入流与字符编码
    JedisCluster cluster = RedisUtils.getClusterConn();
    String[] line = null;
    while (br.hasNext()) {
        String s = br.next();
        line = RedisUtils.split(s);
        String key = "";
        for (int i = 0; i < keyIndex.length; i++) {
            key += line[keyIndex[i]];// TODO:如果有必要，添加分隔符
        }
        cluster.setnx(key, s);
    }
    RedisUtils.clusterClose(cluster);
}`

拜谢！！！
