Question

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。

我已使用Microsoft SQL Server Management Studio连接到数据库，以确保数据库正常运行，并且主机/用户名/密码都正确无误。此外，我已确保端口已打开，并且MSSQL位于另一端，具有以下内容。

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

关于我应该从哪里开始的任何建议？我无法找到有关此错误的任何文档。感谢

我目前正在尝试使用FreeTDS中的OSQL来验证SQL服务器是否可访问。将根据我的发现更新这篇文章。

经过大量搜索并与许多人交谈后，我确定此问题是由端口被阻止引起的。我仍然不能100％确定为什么会出现这种错误。如果我尝试使用无效的用户名或密码，它会成功告诉我它们无效。它只是在实际查询端口受限制时。很可能使用不同的端口。
