[~stanleyxu2005] I took the liberty to create a ticket for the issue you raised today.

Also see a related ticket where we want to expose this balancing step to the connector api in future

> The balancing of the record to the loaders in done internally in SQOOP today
> While writing the Kite Connector Qian noticed that this is not done fairly.
> While I am testing kite connector, I allocated 2 loaders. I thought data will be divided by 50% and 50% to both loaders. But actually the second loader does nothing, because its DataReader does not have any data to provide. Is it by design?
> >> About loaders do not have data in a balanced way.
> My scenario is 4 "jdbc_mysql" extractors to extract 100k row data (10MB). There are 2 Kite loaders to read data.
> This must be a bug that needs to be fixed in SQOOP
