Met with Lefty this afternoon and she was kind to spend time to add my documentation to the site - since I still don't have editing privileges :-)
Please review the new wikidoc about LZO compression in the Hive language manual. If anything is unclear or needs more information, you can email suggestions to this list or edit the wiki yourself (if you have editing privileges). Here are the links:
1. Language Manual<https://cwiki.apache.org/confluence/display/Hive/LanguageManual> (new bullet under File Formats)
2. LZO Compression<https://cwiki.apache.org/confluence/display/Hive/LanguageManual+LZO>
3. CREATE TABLE<https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateTable> (near end of section, pasted in here:)
Use STORED AS TEXTFILE if the data needs to be stored as plain text files. Use STORED AS SEQUENCEFILE if the data needs to be compressed. Please read more about CompressedStorage<https://cwiki.apache.org/confluence/display/Hive/CompressedStorage> if you are planning to keep data compressed in your Hive tables. Use INPUTFORMAT and OUTPUTFORMAT to specify the name of a corresponding InputFormat and OutputFormat class as a string literal, e.g., 'org.apache.hadoop.hive.contrib.fileformat.base64.Base64TextInputFormat'. For LZO compression, the values to use are 'INPUTFORMAT "com.hadoop.mapred.DeprecatedLzoTextInputFormat" OUTPUTFORMAT "org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat"' (see LZO Compression<https://cwiki.apache.org/confluence/display/Hive/LanguageManual+LZO>).

It will be great if I could get edit privileges
