Veena Basavaraj commented on SQOOP-1602:
----------------------------------------
Still not sure I agree if this is non issue
See @jarcec comment in https://issues.apache.org/jira/browse/SQOOP-1938
if default is 10 mappers and loaders is not set, then its default is 0 i.e no
reducers, So I am not sure how you saw that it creates 10 loaders? did you set
this value to 10 as well.
> Sqoop2: Fix the current balancing across Loaders internal to Sqoop

>
> 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.
