Daniel Voros commented on SQOOP-3134:
-------------------------------------
Just ran into this. Instead of introducing a new option, this could probably
also be controlled with {{--class-name}}. It would only need a small change in
the code path changed by SQOOP-2783 to also check for {{className == null}}.
