 you need to give the datanode http port,Like below
 
 
 
 
 curl -i -X PUT -T /home/levi/3 "http://localhost:50075/webhdfs/v1/levi/3?op=CREATE"
 
 
 
 
 Syntax for writing file using webhdfs:
 
 
 Create and Write to a File
 • Step 1: Submit a HTTP PUT request without automatically following redirects and
 without sending the file data
  curl -i -X PUT "http://<HOST>:<PORT>/webhdfs/v1/<PATH>?op=CREATE
 [&overwrite=<true|false>][&blocksize=<LONG>][&replication=<SHORT>]
 [&permission=<OCTAL>][&buffersize=<INT>]"
 
 
 
  Step 2: Submit another HTTP PUT request using the URL in the Location header with
 the file data to be written
 
 
 
  curl -i -X PUT -T <LOCAL_FILE>
 "http://<DATANODE>:<PORT>/webhdfs/v1/<PATH>?op=CREATE..."

 Subject: Put a file to Hadoop with WebHDFS ?
 
 
 
  When i use the WebHDFS, i wanna put a file to Hadoop. my curl command:
 curl -i -X PUT -T /home/levi/3 "http://localhost:50070/webhdfs/v1/levi/3?op=CREATE"
 
 
 But i got a return:
  HTTP/1.1 100 Continue
 
 
 HTTP/1.1 307 TEMPORARY_REDIRECT
 Content-Type: application/octet-stream
 Location: http://58.53.211.46:50075/webhdfs/v1/levi/3?op=CREATE&overwrite=false
 Content-Length: 0
