SQOOP将CSV导出到MySQL失败

我有HDFS中的CSV文件，其中的行如下：

"2015-12-01","Augusta","46728.0","1"

我正在尝试将此文件导出到MySQL表

CREATE TABLE test.events_top10(
   dt VARCHAR(255),
   name VARCHAR(255),
   summary VARCHAR(255),
   row_number VARCHAR(255)
  );

使用命令：

sqoop export  --table events_top10 --export-dir /user/hive/warehouse/result --escaped-by \" --connect ...

此命令失败，出现错误：

在我不使用\“参数转义的情况下，MySQL表包含如下行

"2015-12-01" | "Augusta"       | "46728.0" | "1" 

您能解释一下如何将CSV文件导出到MySQL表中而不使用双引号吗？

我必须同时使用--用\转义和--用“\”括起来 所以正确的命令是

sqoop export  --table events_top10 --export-dir /user/hive/warehouse/result  --escaped-by '\\' --enclosed-by '\"'  --connect ...
