Hi, There: I wonder if it is possible to run map-reduce again hive's raw data.hive supports hql, but sometimes, I want to run map-reduce to do more sophisticated
processing than those simple hql can handle. In that case, I need to run my own custom map-reduce job against hive's raw data.I wonder if that is possible. The key issue is where to find those files and how to deserialize them.
Can anybody point me into the right location to find the API ?
Jimmy.
