话不多说，直接上代码：

import java.util.HashSet;
import java.util.Properties;
import java.util.Set;

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;
/**
 * define redis handlers
 * 
 * @author dmvoishi
 * @since  20181024
 * @category initRedisCluster addNodes getJedisCluster
 */
public class RedisUtil {

	public static JedisCluster initRedisCluster(Properties prop) {
		// 根据配置文件实例化一个集群
		GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();
		String NODE_LIST = prop.getProperty("NODE_LIST").trim();
		Set<HostAndPort> nodes = addNodes(NODE_LIST);

		String MAX_WAIT = prop.getProperty("MAX_WAIT");
		String MAX_IDLE = prop.getProperty("MAX_IDLE");
		String TIME_OUT = prop.getProperty("TIME_OUT").trim();
		String MAX_ACTIVE = prop.getProperty("MAX_ACTIVE");

		poolConfig.setMaxTotal(Integer.parseInt(MAX_ACTIVE));
		poolConfig.setMaxIdle(Integer.parseInt(MAX_IDLE));
		poolConfig.setMaxWaitMillis(Integer.parseInt(MAX_WAIT));
		poolConfig.setJmxEnabled(true);
		poolConfig.setTestWhileIdle(true);
		poolConfig.setTestOnBorrow(true);
		poolConfig.setTestOnReturn(true);
		JedisCluster jedisCluster = new JedisCluster(nodes,
				Integer.valueOf(TIME_OUT), poolConfig);
		return jedisCluster;
	}

	private static Set<HostAndPort> addNodes(String nodes) {
		// TODO Auto-generated method stub
		Set<HostAndPort> nodeList = new HashSet<HostAndPort>();
		String[] node = nodes.split(",");
		for (int i = 0; i < node.length; i++) {
			if (null != node[i]) {
				String[] url = node[i].split(":");
				nodeList.add((new HostAndPort(url[0].trim(), Integer
						.valueOf(url[1]))));
			}
		}
		return nodeList;
	}

	public static JedisCluster getJedisCluster() {
		String redisConfigPath = "hdfs:///user/hdfs/redis.cfg";
//		String path = "C:/config/redis.cfg";
		Properties redisProp = CommonUtils
				.getPropertiesFromHDFS(redisConfigPath);
//		 .getPropertiesFromLocal(path);
		JedisCluster jedisCluster = RedisUtil.initRedisCluster(redisProp);
		return jedisCluster;
	}
}
