我正在尝试使用 Sqoop 连接到 Microsoft SQL Server。我按照Sqoop Connector和JDBC Driver的说明安装了 Microsoft 的 JDBC 驱动程序。接下来我尝试列出服务器上的数据库。我尝试了以下命令：
sqoop list-databases --connect 'jdbc:sqlserver://<HOST>' --username <USER> --password <PASS>
sqoop list-databases --connect 'jdbc:sqlserver://<HOST>;username=<USER>;password=<PASS>'
sqoop list-databases --connect 'jdbc:sqlserver://<HOST>;username=<USER>;password=<PASS>' --username <USER> --password <PASS>
这些命令中的每一个都会产生相同的错误消息。

我已经使用 Microsoft SQL Server Management Studio 连接到数据库，以确保数据库正在运行并且主机/用户名/密码都正确。此外，我已确保端口已打开，并且 MSSQL 位于另一侧，如下所示。
sudo nmap -sS -p 1433 <HOST>
Starting Nmap 5.21 ( http://nmap.org ) at 2013-01-02 11:04 PST
Nmap scan report for <HOST> (<HOST IP>)
Host is up (0.00070s latency).
rDNS record for <HOST IP: <HOST FQDN>
PORT STATE SERVICE
1433/tcp filtered ms-sql-s
Nmap done: 1 IP address (1 host up) scanned in 0.33 seconds
关于我应该从这里去哪里的任何建议？我无法找到有关此错误的任何文档。谢谢
我目前正在尝试使用 FreeTDS 中的 OSQL 来验证 SQL 服务器是否可以访问。将用我的发现更新这篇文章。
