parse_url 0.5.0 Regression?
We have a query like...
SELECT parse_url(url, 'QUERY:q') as query FROM table
I'm sure this used to work in hive 0.4.1 and the docs suggest that 'QUERY:key' should extract the relevant key from a query string but it always seems to return NULL in 0.5.0 is this a regression? or maybe the parse_url() API has changed?
Thanks,
Andy

Thanks, this works so I assume it's the wiki that is incorrect...
http://wiki.apache.org/hadoop/Hive/LanguageManual/UDF#String_Functions
I don't seem to be able to edit the page so should I file a Jira issue for this?

Hi Andy,
SELECT parse_url(url, 'QUERY', 'q') as query FROM table
You can specify a query key. I did not test it in vanilla Hive 4.x but it
works in Cloudera's Hive RPM(0.4.1)
