在Cloudera中使用sqoop將數據從HDFS導出到mysql時作業失敗

[英]Job fails on exporting data from HDFS to mysql using sqoop in Cloudera

 原文  2018-06-10 17:59:20  8   1    mysql/ hadoop/ sqoop/ cloudera

問題描述

我正在導出HDFS位置/ user / training / sqoop_import / departments_export目錄中存在的department_export文件的HDFS數據。 以下是文件中存在的記錄。 

2,Fitness
3,Footwear
4,Apparel
5,Golf
6,Outdoors
7,Fan Shop
8,Development
1000,Admin
1001,Books

我想將數據導出到名為Departments_export（department_id int，department_name varchar）的mysql表。 該表已經包含以下數據 

mysql> select * from departments_export;
+---------------+-----------------+
| department_id | department_name |
+---------------+-----------------+
|             2 | Fitness         |
|             3 | Footwear        |
|             4 | Apparel         |
|             5 | Golf            |
|             6 | Outdoors        |
|             7 | Fan Shop        |
|             8 | Development     |
|          1000 | Admin           |
+---------------+-----------------+

我正在運行以下命令進行sqoop導出 

sqoop export \
--connect "jdbc:mysql://quickstart.cloudera:3306/retail_db" \
--username retail_dba \
--password cloudera \
--table departments_export \
--export-dir /user/training/sqoop_import/departments_export \
--batch \
-m 1 \
--update-key department_id \
--update-mode allowinsert \

我在命令提示符下獲取以下日志。

如果沒有為department_id創建主鍵，您是否在department_export表上具有主鍵。

嘗試這個。

sqoop export \\ --connect“ jdbc：mysql：//quickstart.cloudera：3306 / retail_db” \\ --username retail_dba \\ --password cloudera \\ --table department_export \\ --update-key department_id \\ --update-mode allowinsert \\ --export-dir /user/training/sqoop_import/departments_export/departments.txt \\ --fields-terminated-by ='，'-m 1 \\

我已經嘗試過，並且工作正常。
