通过 微软 pai-fs 上传数据到HDFS （Microsoft OpenPAI）

 准备环境

（个人使用记录，方便下次使用查阅~~）

首先保证PAI是登陆状态：

进入GitHub项目所在地址：

https://github.com/Microsoft/pai/

然后切换分支到 

具体 使用文档再这里：

https://github.com/Microsoft/pai/tree/pai-0.5.y/pai-fs

将代码clone下来后执行：

`python pai-fs.py --config host=xxx.xxx.234.79 port=50070 user=root`（配置Server）

上传数据到HDFS

进到pai-fs.py目录下（也可以直接绝对路径），然后通过 ：

python pai-fs.py + 参数 +路径

进行数据上传

具体使用方法：

（Github README.md）

example use:
  pai-fs --config host=10.0.3.9 port=50070 user=root         -- store hdfs config
  pai-fs -ls hdfs://                                         -- list the contents of a root HDFS directory 
  pai-fs -ls hdfs:// --host 10.0.3.9                         -- list the contents of a root HDFS directory with host specified
  pai-fs -ls hdfs:// --host 10.0.3.9 --port 50070 --user root    -- list the contents of a root HDFS directory with host, port and user specified
  pai-fs -ls -r hdfs://                                      -- list the contents of a root HDFS directory, recursively 
  pai-fs -mkdir hdfs://mydir/mysubdir/mysubdir2              -- makes mysubdir2 and all directories along the way 
  pai-fs -rm hdfs://mydir/mysubdir/myfile                    -- removes myfile from mysubdir 
  pai-fs -rm hdfs://mydir/mysubdir                           -- removes mysubdir and all files and directories in it 
  pai-fs -cp c:mylocalfile hdfs://mydir/myremotedir         -- copy mylocalfile into myremotedir 
  pai-fs -cp -r c:mylocaldir hdfs://mydir/myremotedir       -- copy mylocaldir into myremotedir, recursively 
  pai-fs -cp -r c:mylocaldir* hdfs://mydir/myremotedir     -- copy mylocaldir's contents into myremotedir, recursively 
  pai-fs -cp c:mylocaldir\a hdfs://mydir/myremotedir/b     -- copy file a from mylocaldir to myremotedir and rename to b 
  pai-fs -cp -r hdfs://mydir/myremotedir c:mylocaldir       -- copy myremotedir into mylocaldir, recursively 
  pai-fs -cp -r hdfs://mydir/myremotedir/* c:mylocaldir     -- copy myremotedir's contents into mylocaldir, recursively 
exit code:
  0   -- Success 
  1   -- An exception happened during the operation including bad connection 
  2   -- PAI_VC environment variable not set to valid VC or insufficient/invalid command line argument(s) 
  3   -- Path not found 
  4   -- Unauthorized access 
  5   -- Path not empty 
  6   -- Check failed after operation 
  100 -- Failed to copy too many times 
  101 -- Failed to concat chunks into file
