我想使用sqoop将数据从mysql导入远程配置单元。我已经在中间件机器上安装了sqoop。运行此命令时:

sqoop import --driver com.mysql.jdbc.Driver --connect jdbc:mysql://192.168.2.146:3306/fir --username root -P -m 1 --table beard_size_list --connect jdbc:hive2://192.168.2.141:10000/efir --username oracle -P -m 1 --hive-table lnd_beard_size_list --hive-import;

这个命令正确吗?我可以将数据从远程mysql导入远程配置单元吗?
当我运行此命令时,它会继续尝试连接到资源管理器:

它试图连接的端口是8050,但实际的端口是8033。我怎样才能解决这个问题?

为什么在代码中添加了两次-connect语句?尝试以下代码: sqoop import --driver com.mysql.jdbc.Driver --connect jdbc:mysql://192.168.2.146:3306/fir --username root -P -m 1 --split-by beard_size_list_table_primary_key --table beard_size_list --target-dir /user/data/raw/beard_size_list --fields-terminated-by "," --hive-import --create-hive-table --hive-table dbschema.beard_size_list ###注:
创建配置单元表–确定如果配置单元表已存在,则设置作业是否会失败。在这种情况下,如果您创建了hiveexternaltable并设置了targetdir路径,它将起作用

请尝试以下命令:

请检查以下属性是否设置为 yarn-site.xml 正确地

<name>yarn.resourcemanager.address</name>
<value>192.168.2.191:8033</value>
