[英]WebSocket connection failed. Error during WebSocket handshake - socketjs
[英]TCP/IP connection to the port is failed. sqoop jdbc connection error
当我尝试运行sqoop命令导入时
sqoop import --connect jdbc:sqlserver://localhost/db_name--username
user--password user--table table_name.
我收到以下错误。
ERROR: The TCP/IP connection to the host 127.0.0.1, port 1433 has failed. Error: "Connection refused: connect. 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. Make sure that TCP connections to the port are not blocked by a firewall.".
我的命名管道和TCP / IP均已启用,并且具有端口1433。SQLServer TCP / IP协议也具有端口1433。我创建了防火墙入站和出站规则以允许连接。仍然出现相同的错误。
请尝试将sqljdbc42.jar添加到sqoop lib路径并添加
--driver com.microsoft.sqlserver.jdbc.SQLServerDriver
到您的sqoop导入命令。
还要确保db_name和--username之间应该有一个空格,并且username和--password之间应该有一个空格,并且在命令末尾没有点。
