我正在尝试通过 SQOOP 连接 SQL 服务器，但出现以下错误：
sqoop import --connect 'jdbc:sqlserver://localhost:1433;username=kashif;password=sqoop;database=Northwind' --table Department -m 1;
13/09/26 04:41:22 INFO SqlServer.MSSQLServerManagerFactory: Using Microsoft's SQL Server - Hadoop Connector

Error: "Connection refused. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port.

我已经下载了 sqoop sql 连接器并将它也放在 /usr/lib/sqoop/lib 文件夹中。
我还检查了是否为 TCP 连接启用了端口 1433。
你能指导我吗？
