hadoop搭一个单机模式测试复制文件出错，

搜诶符合你

主要是执行 bin/hadoop fs -copyFromLocal /home/hadp/app/hadoop/test-in/*.txt input
   刚刚学习hadoop 但不知道问题出在哪愁死
    http://localhost:500030/ 和http://localhost:500070 访问没问题
下面是错误的信息
  [hadp@localhost hadoop]$ bin/hadoop fs -copyFromLocal /home/hadp/app/hadoop/test-in/*.txt input
