Project: Sqoop
Issue Type: Bug
Reporter: Veena Basavaraj
Assignee: Qian Xu
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.
