> The {{Matcher.getMatchingData}} method is expected to rearrange record fields 
> according to the FROM and TO schema. Currently here is an extra step in the 
> implementation, which will reset any {{null}} {{"NULL"}} {{"null"}} 
> {{"'null'"}} or {{""}} field to null. 
> As there is no comment or documentation about this, I guess it is some 
> undocumented special handling. [Here is some 
> discussion|https://issues.apache.org/jira/browse/SQOOP-1811?focusedCommentId=14270755&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14270755].
> I think this check should not belong here. I propose to remove it. As the 
> method will be called very frequently, the code removal will have performance 
> advance. Thanks [~jerrychenhf]
