sudhir commented on SQOOP-1171:
-------------------------------

This is really helpful feature, any idea when this is going to be committed? Any table alterations
are pain right now as we need to maintain column in sequence. If needed i can help in doing
code changes, in order to get it committed.

> 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
