database - sqoop 从 db2 特定模式导入所有到配置单元

Question

我尝试使用以下命令行从 DB2 中的特定模式导入所有表。

sqoop import-all-tables  --username user --password pass \
--connect jdbc:db2://myip:50000/databs:CurrentSchema=testdb \
--driver com.ibm.db2.jcc.DB2Driver  --fields-terminated-by ',' \
--lines-terminated-by '\n' --hive-database default --hive-import --hive-overwrite \
--create-hive-table -m 1;

遇到以下错误

命令:

 sqoop import-all-tables \
 --driver com.ibm.db2.jcc.DB2Driver \
 --connect jdbc:db2://myip:50000/databs \
 --username username --password password \
 --hive-database default --hive-import --m 1 \
 --create-hive-table --hive-overwrite

import-all-tables 工具将一组表从 RDBMS 导入到 HDFS。来自每个表的数据存储在 HDFS 中的单独目录中。

要使 import-all-tables 工具有用，必须满足以下条件:

• 每个表必须有一个单列主键。
• 您必须打算导入每个表的所有列。
• 您不得打算使用非默认拆分列，也不得通过 WHERE 子句强加任何条件。
