上传文件到hadoop出问题

初学者，网上搜了好久都没搜到怎么解决

[hadoop@centos7 hadoop]$ hadoop  fs  -put  README.txt  master:/input
put: No FileSystem for scheme "master"
[hadoop@centos7 hadoop]$ ls
bin  etc  include  input  lib  libexec  LICENSE.txt  logs  NOTICE.txt  output  README.txt  sbin  share  tmp
[hadoop@centos7 hadoop]$ hadoop fs -ls / 
Found 2 items
drwxr-xr-x   - hadoop supergroup          0 2022-03-23 09:21 /input
drwxr-xr-x   - hadoop supergroup          0 2022-03-23 08:56 /test

先看这样能不能传

hadoop  fs  -put  README.txt  /input

master: 没必要吧

不用master也可以呀。
你先开启hadoop和yarn
上传的时候
hdfs dfs - put 本地路径 hdfs路径
