title: Error in uploading data to HDFS Fiware Cosmos global Instance
body: <p>I am trying to launch a cosmos instance following this document:<a href="http://fiware-cosmos.readthedocs.io/en/latest/quick_start_guide_new/index.html" rel="nofollow noreferrer">http://fiware-cosmos.readthedocs.io/en/latest/quick_start_guide_new/index.html</a>.
  The first step is executed successfully and i got a access token using which i create a cosmos account acc. to 2nd step and receive this response:
  {"organizations": [], "displayName": "varun143", "roles": [], "app_id": "45bed173b2f8482aa15b22556c057112", "isGravatarEnabled": false, "email": "manchandavishal143@gmail.com", "id": "varun143"}.</p>
  
  <p>Now i follow the 3rd step i.e creating a new dir using this command:curl -X PUT "<a href="http://storage.cosmos.lab.fiware.org:14000/webhdfs/v1/user/varun143/testdir?op=MKDIRS&amp;user.name=varun143" rel="nofollow noreferrer">http://storage.cosmos.lab.fiware.org:14000/webhdfs/v1/user/varun143/testdir?op=MKDIRS&amp;user.name=varun143</a>" -H "X-Auth-token: my acess token" | python -m json.tool and get this response: 
   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                   Dload  Upload   Total   Spent    Left  Speed
    0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
  curl: (52) Empty reply from server
  No JSON object could be decoded.</p>
  
  <p>then i create a testdata.txt file in my local &amp; write some data in it as per document and run this command:curl -v -X PUT -T testdata.txt "<a href="http://storage.cosmos.lab.fiware.org:14000/webhdfs/v1/user/varun143/testdir/testdata.txt?op=CREATE&amp;user.name=varun143" rel="nofollow noreferrer">http://storage.cosmos.lab.fiware.org:14000/webhdfs/v1/user/varun143/testdir/testdata.txt?op=CREATE&amp;user.name=varun143</a>" -H "Content-Type: application/octet-stream" -H "X-Auth-token: my acess token" and get this response attach in this image url:<a href="https://imgur.com/uiWU5qr" rel="nofollow noreferrer">https://imgur.com/uiWU5qr</a> which is not as per document.Now where am i wrong &amp; how to resolve this.Also how can i access cli or GUI  of this instance.Thanks in advance.</p>
