Description

As far as I know, Sqoop can't Specify the maximum amount of DB bandwidth that one Sqoop process can utilize for the import/export purpose in term of the number of bytes per second. For some cases such as online applications, DB bandwidth is very important. If one Sqoop process uses most of DB bandwidth, other apps based on the same DB will suffered a lot. So I want to provide a small patch, which is very useful for my case. When starting sqoop import/export tasks, you just need to give an argument (-Dsqoop.db.bandwidth=5242880, means specifying bandwidth to 5M) after import or export tool name, for example:
$bin/sqoop import -Dsqoop.db.bandwidth=5242880 --connect jdbc:mysql://192.168.1.28:9001/db_name --table t_order --hbase-table t_order --column-family f --hbase-create-table --username 'root' --password 'root' --m 3
