我正在尝试运行sqoop从mssql中提取数据并将其加载到s3。我正在尝试使用aws emr中的hue ui来实现这一点，我这里的sqoop版本是1.4.6。
这是命令，

import --connect jdbc:sqlserver://xxx.xxx.xx.xx/DataWarehouse --username****--password***--table****_20120101 --target-dir s3://<bucket-name> --hive-drop-import-delims --escaped-by "\\"

我已经将SQLJDBC驱动程序放在/usr/lib/sqoop/lib/中，并将相同的jar文件sqljdbc4.jar放在“/user/oozie/share/lib/lib{timestamp}/sqoop”中。一切似乎都很好，但我不知道为什么，我运行上面的命令，作业说成功，但没有数据加载到s3，当我查看日志，这是我看到的错误，
