Jarek Jarcec Cecho commented on SQOOP-1171:
-------------------------------------------

Thank you [~kostiantyn] for the detailed description! I do understand the use case now. The
patch looks quite good, would you mind adding a test case to ensure that we won't regress
from this?

> For example, your target table contains the following fields: id, message, country, dtx.
'id' is autoincrement field and 'dtx' set by trigger. So, you have only two columns on HDFS
(message and country). Now you can set them w/ option '--columns message, country' during
export
