When using sqoop export with --update-key and --columns the options are incompatible. For example, given table T1
the code generation utility creates a Java file which fails to compile.
This seems to happen because ConnManager appends all table columns, even those not mentioned on the command-line (see ConnManager.configureDbOutputColumns). As a result, the generated class contains a write method which references class members which do not exist.
I could suggest two possible solutions: 1) either make this case an exception or 2) make the code that appends all remaining table columns optional.
I may be missing something as that code is there for a reason, but I can't see why?
