Description

Here is the query:

SELECT t.lid, '2011-12-12', s_map2json(s_maxmap(UNION_MAP(t.categoryCount), 100)) FROM ( SELECT theme_lid AS theme_lid, MAP(s_host(referer), COUNT( * )) AS categoryCount FROM PageViewEvent WHERE day >= '20130104' AND day <= '20130112' AND date_ >= '2012-01-04' AND date_ < '2012-01-13' AND lid IS NOT NULL GROUP BY lid, s_host(referer) ) t GROUP BY t.lid

Removing the call s_map2json make it work but not by removing s_maxmap, but I don't understand what could be wrong with the implementation of my udf. And I don't know how to debug remote hadoop jobs.
