Subject some wiki docs for UDAF development
Date Mon, 23 Aug 2010 18:22:35 GMT
Mayank Lahiri, a summer intern here at Facebook, wrote up some usage docs on a few of the new
functions he added.  I'm linking them here in case others find them useful.

http://wiki.apache.org/hadoop/Hive/StatisticsAndDataMining

He also wrote up some notes on the overall process of writing your own UDAF:

This also includes some notes from Arvind Prabhakar on interface evolution for the UDAF resolver.
