> Netezza Direct import Mapper is not sensitive to {{columns}} option. The parameters passed
to {{--columns C1,C2,C3,C4}} are ignored by {{NetezzaExternalTableImportMapper}}. 
> [NetezzaExternalTableImportMapper|https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/mapreduce/db/netezza/NetezzaExternalTableImportMapper.java#L83]
on line 83 is based of [output field names| https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/mapreduce/db/DBConfiguration.java#L420]
instead of input field names. 
> Even when -D mapreduce.jdbc.output.field.names=C1,C2,C3,C4 is set, another bug in [NetezzaExternalTableImportMapper
@ line 128|https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/mapreduce/db/netezza/NetezzaExternalTableImportMapper.java#L128]
duplicates the first column. This is due to the for loop initialization bug where variable
{{i}} should be initialized to {{1}} instead of {{0}}.
