I think it has something to do with the operating system. I didn't have any problem loading columns with type varchar while using centos 5.8. It all of sudden skipped those columns when I jumped to centos 6.3. As Dimitriy suggested, casting varchar to fixed length string would do the magic. 

Thanks, 
Tashi
