John, This article is pretty good: http://www.congiu.com/a-json-readwrite-serde-for-hive/
It looks like you can get access to the information you are looking for in the Properties object passed to the SerDe's initialize method. public void initialize(Configuration conf, Properties tbl) throws SerDeException Look here for an example of usage: https://github.com/rcongiu/Hive-JSON-Serde/blob/master/src/main/java/org/openx/data/jsonserde/JsonSerDe.java Hope that helps.
