sqoop,选择特定列

你可以使用--columns --table --where子句来实现它.样品如下:

sqoop import  
--connect jdbc:oracle:thin:@server1.companyxyz.com:4567/prod/DATABASE=schema1
--username xyz 
--password xyz 
--table customers
--columns cust_id, name, address, date, history, occupation  
--where item>=1234 
--target-dir /tmp//customers
--m 8
--split-by cust_id
--fields-terminated-by , 
--escaped-by \ 
--hive-drop-import-delims  
--map-column-java
  cust_id=string, name=string, address=string, date=string, history=string, occupation=string
