一、GZIP 压缩（默认压缩编码器）

sqoop import 
--connect jdbc:mysql://centos02:3306/OfficialCashMid 
--driver com.mysql.cj.jdbc.Driver 
--username root 
--password sa123_ADMIN. 
--table tadminoperationlog 
--m 2 
--target-dir /jdbcHDFS/TAdminLog_txt_gzip 
--compress  
--fields-terminated-by '\t' 

[root@centos02 bin]# sqoop import --connect jdbc:mysql://centos02:3306/OfficialCashMid --driver com.mysql.cj.jdbc.Driver --username root --password sa123_ADMIN. --table tadminoperationlog --m 2 --target-dir /jdbcHDFS/TAdminLog_txt_gzip --compress  --fields-terminated-by '\t'
