.netcore上的linux odbc连接到配置单元

我正在尝试从linux上的.netcore（1.0.1版）应用程序（Red Hat 7.3 64位）连接到Hive

Program.cs代码：

using System;
using System.Data.Odbc;
using System.Collections;
using System.Collections.Generic;

namespace app
{
   class Program
    {
        static void Main(string[] args)
        {
            var connectionString = "DSN=Hadoop Hive";
            var createTableCommandText = "CREATE TABLE Searches(searchTerm      STRING, userid BIGINT,userIp STRING) " +
                                        "COMMENT 'Stores all searches for data' " +
                                        "PARTITIONED BY(searchTime DATE) " +
                                        "STORED AS SEQUENCEFILE;";

            using (var connection = new OdbcConnection(connectionString))
            {
                using (var command = new OdbcCommand(createTableCommandText, connection))
                {
                   try
                   {

                       connection.Open();

                    // Create a table.
                    command.ExecuteNonQuery();

                    // Insert row of data.
                    command.CommandText = "INSERT INTO TABLE Searches PARTITION (searchTime = '2015-02-08') " +
                                           "VALUES ('search term', 1, '127.0.0.1')";

                    command.ExecuteNonQuery();

                    // Reading data from Hadoop.
                    command.CommandText = "SELECT * FROM Searches";
                    using (var reader = command.ExecuteReader())
                    {
                        while (reader.Read())
                        {
                            for (var i = 0; i < reader.FieldCount; i++)
                            {
                                Console.WriteLine(reader[i]);
                            }
                        }
                    }
                }
                catch (OdbcException ex)
                {
                    Console.WriteLine(ex.Message);
                    throw;
                }
                finally
                {
                    Drop table
                    command.CommandText = "DROP TABLE Searches";
                    command.ExecuteNonQuery();
                }
            }
        }

有人能帮忙解决这个问题吗？驱动程序（用于配置单元的Hortonworks ODBC）在此服务器上运行。此处的ODBC连接库存在问题。

您似乎正在尝试将其作为32位应用程序进行构建和加载，而Hortonworks ODBC for Hive可能不支持这一点。需要查看Hortonworks的文档以了解这一点。

您似乎正在尝试不支持Linux托管环境的第三方ODBC ADO.NET连接器。官方的.NET Core compatible System.Data.Odbc计划用于netstandard2.0，并将很快提供（）。
