.NET HBase REST API客户端库-从MVC5控制器调用

查看上给出的示例代码https://azure.microsoft.com/en-us/documentation/articles/hdinsight-hbase-tutorial-get-started/#use-net hbase rest api客户端库，

我正试图从MVC控制器连接到HBase，如下所示：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Web.Http;
using Microsoft.HBase.Client;
using org.apache.hadoop.hbase.rest.protobuf.generated;
namespace MyHBaseTest.Controllers
{
    [RoutePrefix("api/myhbasetestcontroller")]
    public class MyHBaseTestController : ApiController
    {
        HBaseReader hbase = new HBaseReader();
        [HttpGet]
        [Route("")]
        public IHttpActionResult Index()
        {
            string clusterURL = "https://<yourHBaseClusterName>.azurehdinsight.net";
            string hadoopUsername = "<yourHadoopUsername>";
            string hadoopUserPassword = "<yourHadoopUserPassword>";
            // Create a new instance of an HBase client.
            ClusterCredentials creds = new ClusterCredentials(new Uri(clusterURL), hadoopUsername, hadoopUserPassword);
            HBaseClient hbaseClient = new HBaseClient(creds);
            // Retrieve the cluster version
            var version = hbaseClient.GetVersion();
            Console.WriteLine("The HBase cluster version is " + version);
            return Ok();
        }
    }
}

在调试模式下运行时，当我尝试在浏览器中查看URL/api/myhbasetestcontroller时，它会永远加载页面，而不会在Visual Studio中引发任何异常或任何内容。我等了15-20分钟，但什么都没变。

当我在控制台应用程序中尝试做同样的事情时，它会在几秒钟内获得版本信息：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.HBase.Client;
using org.apache.hadoop.hbase.rest.protobuf.generated;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string clusterURL = "https://<yourHBaseClusterName>.azurehdinsight.net";
            string hadoopUsername= "<yourHadoopUsername>";
            string hadoopUserPassword = "<yourHadoopUserPassword>";
            // Create a new instance of an HBase client.
            ClusterCredentials creds = new ClusterCredentials(new Uri(clusterURL), hadoopUsername, hadoopUserPassword);
            HBaseClient hbaseClient = new HBaseClient(creds);
            // Retrieve the cluster version
            var version = hbaseClient.GetVersion();
            Console.WriteLine("The HBase cluster version is " + version);
        }
    }
}

我只是不明白这到底有什么不同。

你能给我建议吗？

非常感谢。

        // POST: api/Vizzini
    [ResponseType(typeof(string))]
    public async Task<IHttpActionResult> GetResponse(string tweet)
    {
        string s = await Task.Run(() =>
        {
            return ResponseEngine.GetBestResponse(tweet);
        });
        return Ok(s);
    }
