Would be great to see your thoughts [~richard_zhou] as you've submitted the

> Components: connectors/mysql

> mysql connector version 5.1.33

> SQOOP-1400 changed the default behavior for the connector to load everything
> in memory. The only working way to get the old streaming back is to use
> --fetch-size -2147483648 (Integer.MIN_VALUE)
> It would be nice if that could be changed and/or documented that mysql does
> not support a fetch size and does only support row-by-row or loading
> everything in memory
