Ning Zhang commented on HIVE-1659:

Xing, this patch doesn't apply cleanly with the latest trunk. Can you 'svn up' and regenerate
the patch. You may need to resolve any conflicts after 'svn up'.

> The UDF parse_url take s a URL, parse it and extract QUERY/PATH etc from it. However
it can only extract an atomic value from the URL. If we want to extract multiple piece of
information, we need to call the function many times. It is desirable to parse the URL once
and extract all needed information and return a tuple in a UDTF.
