[~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
