Question

我试图在Sqoop for Hadoop中使用generic-jdbc-connector创建一个链接。但是，当我尝试获得数字格式异常时：

sqoop:000> show connector
+----+------------------------+---------+------------------------------------------------------+----------------------+
| Id |          Name          | Version |                        Class                         | Supported Directions |
+----+------------------------+---------+------------------------------------------------------+----------------------+
| 1  | generic-jdbc-connector | 1.99.6  | org.apache.sqoop.connector.jdbc.GenericJdbcConnector | FROM/TO              |
| 2  | kite-connector         | 1.99.6  | org.apache.sqoop.connector.kite.KiteConnector        | FROM/TO              |
| 3  | hdfs-connector         | 1.99.6  | org.apache.sqoop.connector.hdfs.HdfsConnector        | FROM/TO              |
| 4  | kafka-connector        | 1.99.6  | org.apache.sqoop.connector.kafka.KafkaConnector      | TO                   |
+----+------------------------+---------+------------------------------------------------------+----------------------+
sqoop:000> create link --connector generic-jdbc-connector
Invalid command invocation: Missing required option: c
sqoop:000> create link -c generic-jdbc-connector
Exception has occurred during processing command
Exception: java.lang.NumberFormatException Message: For input string: "generic-jdbc-connector"

我使用了来自http://sqoop.apache.org/docs/1.99.7/user/Sqoop5MinutesDemo.html

的示例

有什么想法吗？

Answer 1

请使用以下命令，它应该可以工作。

sqoop:000> create link -connector generic-jdbc-connector

问题：您已多次尝试过。

    1st time : In your command you have given --connector in place of -connector
    2nd time : In place of -connector you have given -c which is wrong, that is the reason you are getting exception.
