Hi Sergio, You are not able to perform such an operation from outside because you have to append to the request an OAuth2 token (and use HttpFS port instead, see later). This is because the WebHDFS interface authentication and authorization mechanisms were recently moved to OAuth2. There was a general announcement, nevertheless if you missed it, you have all the details in this stack overflow.com question: http://stackoverflow.com/questions/31187977/oauth2-access-to-cosmos-webhdfs -in-fiware-lab Additionally, as said, we are using the HttpFS port (14000 instead of 50070) because this allows us to hide the cluster details from the outside. Please, follow the guide above and tell me if you have any doubts. Regarding the enabler documentation, we are working hard to update it, it should be ready in the following days.
