warning: wrong element type nil at 98 (expected array)
warning: ignoring wrong elements is deprecated, remove them explicitly
warning: this causes ArgumentError in the next release
警告：98处的错误元素类型为nil（预期数组）
警告：不推荐忽略错误的元素，请明确删除它们
警告：这会在下一个版本中导致ArgumentError

1)、将需要新增的节点下appendonly.aof、dump.rdb等本地备份文件删除；
2)、同时将新node的集群配置文件删除，即：删除你redis.conf里面cluster-config-file所在的文件；如果是默认的话，那就是删除nodes.conf 文件。
3)、再次添加新节点如果还是报错，则登录新node后,./redis-cli –h 192.168.5.128 –p 7007 对数据库进行清除：
　　192.168.5.128:7007>  flushdb      #清空当前数据库
