Question

我正在尝试使用Sqoop导出Hive表到SQL服务器。我在hive表中有一个字符串字段，SQL服务器中该字段的格式是varchar（255）。在运行以下Sqoop导出时：

sqoop export -Dmapreduce.job.queuename=default
 --connect 'jdbc:sqlserver://IPaddress:portnumber;databasename=mydbname'
 --username xxx 
 --password  xxx 
 --table tablename 
 --export-dir /hive_directory/tablename 
 --columns all_my_columns 
 --input-fields-terminated-by '^' 
 --input-null-string "\\\\N" --input-null-non-string "\\\\N"

我得到以下错误。字段值类似于...... NTL-NATIONAL。感谢任何解析这个值的想法。谢谢。

你试过包含这个论点吗？

--input-lines-terminated-by <char>

即

--input-lines-terminated-by '\n'

Sqoop导出到SQL服务器 - 无法解析字符串值（NTL-NATIONAL）
