Description
Hello,
I'm writing a .net application with C# to programmatically run REST apis against hdfs on fiware but on http POST operations it fails with 401 (access denied). it works for simple GET operations but I'm not sure how to do authentication. From the spec it seems SPEGNA and delegated auth tokens are two options but how do i do this programmatically? I only have my user name and password to go off of. I'm using the RestSharp library to make rest interactions easier.
This code works
var client = new RestClient("http://cosmos.lab.fi-ware.org:14000");
request = new RestRequest("webhdfs/v1/user/<userID>");
request.AddParameter("op", "LISTSTATUS");
request.AddParameter("user.name", "<userID>");
IRestResponse response = client.Execute(request);
var content = response.Content; // raw content as string
this code fails with http 401
var client = new RestClient("http://cosmos.lab.fi-ware.org:14000");
var request = new RestRequest("webhdfs/v1/user/<userID>/structured_data123.txt",Method.PUT);
request.AddParameter("op", "CREATE");
request.AddParameter("user.name", "<userID>");
IRestResponse response = client.Execute(request);
HTTP Status 401 - org.apache.hadoop.security.authentication.client.AuthenticationException: Anonymous requests are disallowed
Thoughts? ideas? thank you in advance!
