How to create a table with collected items in Hive?

Question

This may be really nothing but as i am new to hive. I don't know how to do this in Hive? I am trying to create a external table in hive, in which one of the columns has array as data type. My sample data looks like this:

QuRYeRnAuXM EvilSquirrelPictures 1135 Pets&Animals 252 1075 4.96 46 86 gFa1YMEJFag nRcovJn9xHg 3TYqkBJ9YRk 

Now, here is the problem my columns are '\t' separated and I want the last three columns(gFa1YMEJFag nRcovJn9xHg 3TYqkBJ9YRk) placed in one column namely related_video_ids. I tried and came up with DDL for my table, here's how it looks:

create external table youtube(video_id char(12), uploader string, time_of_est int, 
category string, len int, views int, ratings float, num_of_rat int, comments int,
related_video_ids array<struct<col1:string,col2:string,col3:string>>) row format delimited
fields terminated by '\t' 
collection items terminated by '\t' 
location '/youtube/'; 

But Every time, I write the above Query in Hive I get results like:

QuRYeRnAuXM  EvilSquirrelPictures   1135    Pets & Animals  252     1075    4.96000003815   46  86  [{"col1":"gFa1YMEJFag","col2":null,"col3":null}] 

Please help me to get correct DDL for my table.
