Question

即使在connect参数中提供了远程服务器IP，Sqoop import也会尝试连接到本地mysql

我在下面尝试使用MySQL连接到远程MySQL服务器，它运行正常。我能够探索这些表格。

mysql -u anuser -h 1.133.23.58 -p

当尝试下面的代码时，它试图用＆＃34; anuser＆＃34;连接到本地MySQL实例。这是远程MySQL实例的用户。

sqoop-import -m 1 
--driver com.mysql.jdbc.Driver \\
--connect jdbc:mysql://1.133.23.58:3306/misp \ 
--username anuser \
--password password \
--query "select id, CURDATE() as ref_date, v, score, type, feed from AnDomains where \$CONDITIONS" \
--split-by id \
--hive-drop-import-delims \
--hive-import \
--hive-table testdb.andomains \
--target-dir andomains

但我可以成功连接到sqlserver DB并将数据提取到hive表

Answer 1

您需要从请求连接的主机提供对用户的访问权限。在mysql命令提示符下执行以下命令：

GRANT ALL PRIVILEGES ON *.* TO 'ansuser'@'120.0.0.1' identified by 'passwordhere';

即使在connect参数中提供了远程服务器IP，Sqoop import也会尝试连接到本地mysql
