Review request for Sqoop and Bilung Lee.
Changes
-------
I've fixed my explanation comment to fulfill check style policy.
Summary
-------
I've just tweak code generation to support use case mentioned in the JIRA -
case when both keyword and _keyword columns are present in the same table.
Current code generation code might create many other duplicates because of
dropping of unsupported characters and other transformations. Those advanced
problems might be solved by --query and SQL projections ('column!' AS column2,
'column?' as column3).
This addresses bug SQOOP-430.

> Issue Type: Bug
> Affects Versions: 1.4.0-incubating
> Reporter: Lars Francke

> This is a constructed example but given a table with two columns: {{class}}
> and {{_class}} we get an error message upon running Sqoop:
> {quote}Imported Failed: Duplicate Column identifier specified: '_class{quote}
> This happens because the {{ClassWriter}} rewrites all columns that are
> reserved keywords in Java by prepending a "_".
