> +Question:+
> Remote connection to fiware-cosmos returning authentication error
> +Description:+
> We have a COSMOS account on cosmos.lab.fi-ware.org and can load files locally onto the cluster. 
> However, we are having trouble loading remotely, the instructions we followed on the guide site show the following: 
>   However, using the WebHDFS/HttpFS RESTful API will allow you to upload
>   files existing outside the global instance of Cosmos in FI-LAB. The
>   following example uses HttpFS instead of WebHDFS (uses the TCP/14000
>   port instead of TCP/50070), and curl is used as HTTP client (but your
>   applications should implement your own HTTP client):
> [remote-vm]$ curl -i -X PUT "http://cosmos.lab.fi-ware.org:14000/webhdfs/v1/user/$COSMOS_USER/input_data?op=MKDIRS&user.name=$COSMOS_USER"
> [remote-vm]$ curl -i -X PUT ..etc
> [remote-vm]$ curl -i -X PUT -T etc..
>   
>   As you can see, the data uploading is a two-step operation, as stated
>   in the WebHDFS specification: the first invocation of the API talks
>   directly with the Head Node, specifying the new file creation and its
>   name; then the Head Node sends a temporary redirection response,
>   specifying the Data Node among all the existing ones in the cluster
>   where the data has to be stored, which is the endpoint of the second
>   step. Nevertheless, the HttpFS gateway implements the same API but its
>   internal behaviour changes, making the redirection to point to the
>   Head Node itself.
> However, when we run these commands we get server errors coming back, one example is:
> ~ kari$ -bash: user.name=kdempsey: command not found
> HTTP/1.1 100 Continue
> HTTP/1.1 401 Unauthorized
> Server: Apache-Coyote/1.1

> description This request requires HTTP authentication (org.apache.hadoop.security.authentication.client.AuthenticationException: Anonymous requests are disallowed).
> Apache Tomcat/6.0.32
> Another was a 500 server error. Could please provide the commands for remotely loading a file into the COSMOS shared resource.
> Ultimately we want to take data from our InfluxDB and load into COSMOS, we would like to do it via REST call if possible (otherwise python).
> Many thanks,
