May I get edit permissions?
Thanks.

You can email hive-dev@hadoop.apache.org<ma...@hadoop.apache.org> asking for edit privileges on the Hive wiki.
Here's an example from the archives<http://mail-archives.apache.org/mod_mbox/hive-dev/201304.mbox/%3cCAKHgJS42yQqj54RC8YvzGXbUbiEs7mpV9fDofq2Z3Onfo67zwg@mail.gmail.com%3e>.
Once you have permission, you can use the Edit and Add symbols in the upper right corner of each wiki page.
For page location, I'd have to think it over and check the existing docs. Initial thoughts:
* The Language Manual<https://cwiki.apache.org/confluence/display/Hive/LanguageManual> has a placeholder for file formats which only contains ORC files now.
* Perhaps the DDL section is more appropriate. If so, add a subbullet on the Language Manual page.
* If you don't want it in the Language Manual, just put it on the home page<https://cwiki.apache.org/confluence/display/Hive/Home> and add a link under User Documentation.
* As long as it's somewhere in the Hive wiki tree, the apparent organization can be changed by adding/removing links.
* Many people don't pay attention to the page structure, they just google the topic they're looking for.

Perhaps you'd like to write up your insights in the Hive wiki, and others could add their insights. Then the information would be available to all, immediately.

Hi Programming Hive Book authors
Maybe a lot of u have already successfully implemented this but only these last two weeks , we implemented our aggregations using LZO compression in Hive - MR jobs creating LZO files as Input for Hive ---> Therafter Hive aggregations creating more LZO files as output.
As usual nothing was straight forward :-) Also the other challenge was to neatly tie all into actions in Oozie workflows….but after being underwater for weeks I think I am able to rise above water and breathe !
In the next version of the book , If u guys r planning to add detailed sections on using lzo compression in Hive , let me know…my experiences might be useful :-)
Thanks
sanjay
