Any getting-started with UDAF development

Is it possible to use "count" in Where clause ?

Hi, I am quite new to Hive. I just wonder if a query like this is possible in hive? select * from events where events.pid = '123' having count(events.id) > 2 or more precisely is it possible to use " having count(events.id) > 2" in Hive SQL ? best, /Shahab
