		String key_expire = RedisCarportCloumn.MODE_EXPIRE_PREFIX + result.getGridStakeSeq();
//		jedis.hset(key_expire,CommonConstant.SEND_TIMES_KEY, CommonConstant.SEND_STAKE_MSG_TIMES);//限制主动下发次数
		jedis.hset(key_expire,"SEND_TIMES","3");//限制主动下发次数
//		jedisCluster.hset(key_expire,CommonConstant.SEND_TIMES_KEY, CommonConstant.SEND_STAKE_MSG_TIMES);//限制主动下发次数

		jedis.close();

hset看起来没有值类型不对的样子。后来发现原来是因为redis数据库中已经存在了相同的key， 而且key对应的值类型并不是Hashkey；再调用hset时，就会抛出此错误。（ps：忽想起来，最初设置的key-val   ，后面改为hash-val）

把原来的数据清掉，重新运行就没问题了。
