> 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 ( [~abec] confirmed it.
