Question

我使用下面的命令使用sqoop从oracle导入表到hadoop。但我得到错误。因为我是hadoop的noob，我不知道如何解决它。

sqoop import --connect "jdbc:oracle:thin:@172.16.10.112:1523:TABS" --username testuser1 --password testuser1 --table tabs.user_info --target-dir /tmp –verbose


Generic Hadoop command-line arguments:
(must preceed any tool-specific arguments)
Generic options supported are
-conf <configuration file>     specify an application configuration file
-D <property=value>            use value for given property
-fs <local|namenode:port>      specify a namenode
-jt <local|resourcemanager:port>    specify a ResourceManager
-files <comma separated list of files>    specify comma separated files to be copied to the map reduce cluster
-libjars <comma separated list of jars>    specify comma separated jar files to include in the classpath.
-archives <comma separated list of archives>    specify comma separated archives to be unarchived on the compute machines.

The general command line syntax is
bin/hadoop command [genericOptions] [commandOptions]


At minimum, you must specify --connect and --table
Arguments to mysqldump and other subprograms may be supplied
after a '--' on the command line.

Answer 1

详细信息中的短划线（ - ）是不同的

Answer 2

您不应在表格选择中指定数据库。因为已在连接字符串中选择了数据库TABS，

替换，

--table tabs.user_info

与

--table user_info

请告诉我这是否适合您。
