             Summary:  Sqoop2:  Explicit support for Merge in the Sqoop Job lifecyle
                 Key: SQOOP-1603
                 URL: https://issues.apache.org/jira/browse/SQOOP-1603
             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.
